Doggy for me! I like when the guy takes control and drills me, grabbing a fistful of my hair. I like when he stops too, and encourages me to rock my ass back onto him
I sucked a guy off at a party once in front of a few friends as a dare, not to climax (I could see his frustration) and it was only a few minutes.
I had sex with a guy whilst his roommate watched when I was at uni in his flat. That still turns me on when I think about it
