Yes kind of, the first time I did it was standing in the shower and having never experienced that before my legs went out from underneath me, one other time I was on phone talking naughty an playing and I rolled over not really thinking about anything else and crashed out of bed.
Have you ever had a cramp or muscle pull during sex?
No, I've always had a very set idea of what I think I would enjoy and naturally that has always translated well in practice, the fact that my boundaries are somewhat wide is innate more than anything
Edit: not for sex personally but for fancy dress is fun
Have you ever been denigrated online for opening up about some of the things you like sexually?
I have never had to deal with that so I can't really answer...if my partner didn't want to please me I'd be fine, if she didn't want me to go down on her...
I'll say No and Maybe
