If you'd be a sex-superhero, what would be your sex-superpower?
Try to think of something extraordinary that fits your real abilities in the sheets.
Mine probably would be absolute orgasm (self-)control while doing anal. It's sometimes not easy for me to hold back my orgasm doing PIV, especially while using a condom or after a long dry spell. But with anal sex I could go for hours with full enthusiasm without blowing my load unless I want to. And if I want to It's always there in a range of a few seconds for me to go for.
Well since you mentioned super heros why not mention a comic book https://en.m.wikipedia.org/wiki/Sex_Criminals
In the comic there are people that can temporarily stop time when they orgasm and they use this power to rob a bank.
What I'd want is a transmissible absolute immunity to all sexually transmitted disease.
What I'd have, most likely, is some sort of aura that made guys just lose themselves in the moment, and no matter how long we spent fucking, when it was over no time would have passed in the real world. There would always be time for sex.
And @OP, I would hate to meet you with that superpower. A little bit of anal is the right amount, too long is just unpleasant.
