I've been a masochist for a long time and I love brutal sex and roughing around. I used to get turned on so easily thinking about being beaten and abused. I still do occasionally but...
I had a partner once who was probably the most gentle person I'd ever been with. Light touches. They made me feel vulnerable and small. Sex never felt like just sex - it was like this intricate series of events that amassed in passion every single time. It wasn't rough, it wasn't fast. It was slow and building, and when we were done we'd lay there and just hold each other until he slipped out. Imagining that has been one of my biggest turn ons for a while.
