I was raped when I was 19 - the way UK law stood then had I gone to the police I would also have found myself in the dock for gross indecency as the law didn't recognise the concept of one man raping another.
Verging on twenty years after the original incident it was me ex who pointed out that whether I was top or bottom in a scene, I usually turned it into a rape fantasy. Something, I guess that's easier to do to as a bottom: he'd started off using yes/no stopwords when topping me until he noted that my "no" was his "yes". We switched to traffic light colours to end the confusion. Similarly if I'm topping someone I use traffic light colours: his "no" simply means "yes, Sir, please, Sir, more, Sir".
The rape echoes down the years as every now and then I'll pause and ask the boy if he's ok. I don't want to do this, for fear of bring him back to earth: it's prompted by past experience. In short, it's made me almost reckless in what I'll take as bottom, and as for my attitude as top, I go more for the psychological, setting up things so the bottom can't help but hurt himself.
