I’m the worst student. When I’m not cocking up the task you’ve set me, or getting stroppy because I don’t understand, I’m struggling to concentrate because – God damn my juvenile brain – there’s a teacher, and he’s got such sexy hands and commanding presence and I want to know what it would be like for him to put me over the desk and spank me.

Don’t get me wrong – I listen, I do. But I have such strong connections with school and arousal that there’s an unavoidable physical reaction I get that prevents me from always being the model student.

Teenage kicks right through maths class

Most people have a teacher they used to crush on. I’ve told you about mine before, and the feelings I had for him sit heavily in the back of my mind when I’m in any situation that involves sitting down and listening to a speaker.

But there’s more to the learning/sex association than a hot teacher and my own fluttering eyelashes – school itself was deeply hot.

I was a nerdy child. The one with greasy hair and crap glasses, who sat aching on the sidelines at the school disco, desperate for a boy to rub herself against but never quite cool enough to be asked. Interactions I did have with boys were usually furtive. Geeky guys drew the line at being associated with me and I, keen to ape the mysterious heirarchy of popularity, didn’t want to be too publicly associated with them for similarly misguided childish reasons.

So: furtive secrecy all the way.

A touch under the desk. An elbow brushing my chest when a boy leant across to get a pen. A five-minute grope behind the sheds on the playing fields until the bell rang for the end of lunchtime and I groaned and nearly melted into a puddle of my own frustrated angst.

Maths class was the best. I sat sandwiched between two friends, who used my desperation for in-class touching as an outlet for their own rampaging hormonal curiosity. We’d flirt. We’d touch. We’d scrawl notes to each other in the back of workbooks:

“I had a wank about you last night.”

And all the time knowledge was being hurled at me. Equations, formulae, words, techniques, answers. I wrote it down. I tried to focus. And I tried to wrench my brain away from the fact that oh God his hand was on my thigh and his fingers were so close and if I just shift a little bit to the right he’ll feel the wetness seeping through my knickers.

The hotness of learning doesn’t go away

I’m not young any more, and I can make it through a conference call or a powerpoint presentation without dripping concentrated lust through the crotch of my jeans. But the association, now made, cannot be broken. I’m the one sitting at the back noting down words and feeling hot with the physical memory of classes in which the boys deigned to touch me. The rigid stiffness of sitting still gives me an awareness of all of my muscles, my limbs, the rise and fall of my chest, the pulsing throb of my heartbeat kicking against the seams of my clothes.

It can’t just be me – it’s definitely not just me, right? The combination of youthful memories and adult fantasies means that when I’m at the back of the room I’m more vulnerable to instinctive arousal than ever. I’ll take notes, listen, and ask pertinent questions, but when I shift in my seat it’s not always because I’m uncomfortable.

Eroticon 2014

As you might have guessed, this weekend I was at Eroticon – a spectacular sex writing conference. I kept a bit quiet about going because I don’t like to broadcast where I am at any given point, but this post won’t go live until I’ve left. Alongside writhing in exquisite horniness for two solid days, I learned many fantastic things from some truly brilliant and lovely people. I’m sure I will miss some people off the list because I am fallible and useless and editing this on my phone – but thank you to everyone I met for being kind and putting up with my anxious mumbling.

Ruby Goodnight, Cara Sutra, Emily Dubberley and Mia More – all incredibly lovely people who taught me many things about online writing, press, and working the machine.

Molly and DomSigns – they are like the Sid + Nancy of sex blogging. Follow both of them, and if you get to meet them one day then you are incredibly lucky – try not to be as inarticulate and starstruck as I was.

Pandora Blake, Myles Jackman and Zak Jane Keir – they talked very wisely about censorship, and taught me things that scared the crap out of me. Zak wins the award for ‘quote of the weekend’: “If censorship is the answer, then it was a fucking stupid question.”

Victoria Blisse, KD Grace and London Faerie – sometimes you need to step outside what you know, and these people all taught me really interesting things about perceptions of sex outside my own limited experience and opinions.

The lovely people at Belle de Soir and Doxy who gave me one of these incredibly powerful fuckwands. I have never had a sex toy that comes this close to being an actual power tool, so expect a post soon in which I describe, in excessive detail, the terrifyingly awesome things I expect it’ll do to my cunt.

The excellent and hilarious HarperElliot and Gryphon taught me how to read porn out loud, so if you’re interested in hearing a blog post rather than reading it, let me know and I’ll try to record something using their excellent advice.

And a final, most heartfelt thank you to the awesome Ruby, who is the hard work and exceptional organisation behind Eroticon. You are spectacular, and thank you so much for having me.

Well done, humanity, you have done me proud. When The Guardian printed this problem page question from a lady who fantasises about being passed around a group of old, obese men who struggle to get erections, I expected the comments section to be a sulphur-stinking pit of hellish mockery.

Because that’s generally what happens when someone admits to a fantasy that doesn’t fit with one of our traditional stories. I was going to say ‘an uncommon fantasy’ but to be honest, given the horror this woman feels about admitting to her fantasy I’d have to go out on a limb and say this dream may be far more common than we think.

To my surprise, though, the comments were mostly sensible.

“Why on earth would you feel guilty? And why do you think of yourself as ‘sick’? Those are strong statements. Your sex life is fine and If you don’t want to share your fantasy with your fiancė then don’t.”

“Of all the fantasies I’ve ever heard, this has got to be one the of the most easily realizable.”

Hot fantasy about old obese men

One of my favourite wank fantasies involves a pair of older guys. Ideally (because I love my backstory) in a position of power or authority over me. Traditional scenes begin in an office, where I play up to patriarchal stereotypes by wearing an incredibly short skirt and bringing coffee into the business meeting being held by these two men.

One of them is usually relatively young – thirty or forty – and he’s staring at my arse like he wants to bite it. The other guy is older, perhaps fifty or sixty, calls me ‘sweetheart’ and leers inappropriately through the stretched fabric of my tight shirt as I bend down to put the coffee tray on the table. One of them, inevitably, slaps my arse.

The older guy (my boss) remarks on how obedient I am, and asks me to show his friend just how willing I am to please. He leans back in his chair, unzips his flies, and pulls out a thick, twitching, semi-flaccid cock. I drop to my knees in front of him, and as he croons ‘that’s it’, I slip his dick into my mouth.

He’s big and looks bigger – looming over me with his paunch and his jowls and his filthy, smug grin. He knows I feel obliged to do this to him, and that’s part of the turn on. The other part being, of course, the ability to show off his toy to his friend.

As I suck him harder, he pulls my head down so that my lips are around the base of his cock, his thick head pushing hard up against the back of my throat. Occasionally he makes small grunts to show just how much he’s enjoying it, or mutters ‘good girl, just like that’ through gritted teeth. But in between these interjections he keeps talking to his friend.

“Good, isn’t she?”

“Absolutely. I should get one for my office.”

“You can… ungh… you can have a turn when I’m done if you like. She’d be only too happy to oblige.”

The friend sits there watching, stroking at the erection that’s pressing against the crotch of his suit trousers. But I don’t fuck the friend – I never get a chance. Because as I picture the thick, desperate hardness of the older guy’s dick pushing solidly against the back of my throat, and imagine the strangled grunting sounds he makes as he comes, and conjure up the feeling of his thick, hot spunk gushing down the back of my throat… that’s usually the moment when I come.

The younger guy rarely needs to fuck me in order to complete the fantasy.

Being ashamed of fantasies

So, to all the Guardian readers who refrained from making comments along the lines of ‘ewww’, when someone confessed to fantasies of obese older men, I salute and thank you. I guarantee you that this particular fantasy isn’t limited to one individual, and that there are many more people who like that sort of thing.

To the woman who wrote the letter in the first place: don’t be upset. Most people have at least one thing that gets them horny in secret but that they wouldn’t want to shout from the rooftops. There’s no need to be ashamed of if you get off on something unusual. You’re not hurting anyone by doing it, you’re just pushing the specific set of buttons that happen to have been wired in your brain that way.

As one of the Guardian commenters so excellently put it:

“There is nothing wrong in a fantasy, like emotions, they are not good or bad. they just are. We can’t control them but they do no harm to others (it is our actions that may hurt others, not the thoughts in our heads), so whatever they are they are nothing to be ashamed of.”
