Typically, I enjoy rough sex (although, I AM still human, and prefer making love at times). My boyfriend now is open about being rough, and I'm pretty sure I changed his mind about what is "rough sex."
Before me, he would just go fast, and hard, since when most people refer to rough sex, that is what they are referring to.
I am a little different though, and enjoy being abused in bed sometimes. He has been known to spank and/or slap me mid-coitus (always with my permission before we start!!). I also enjoy being choked, and having my hair pulled. It seems almost animalistic, which is a huge turn on!
