Other than my first time and a couple special occasions I've always preferred having rough sex. After that I found that its so much hotter when I'm just crushing a girl(excuse my choice of words). Doing a girl at short notice feeling the aggression of each other always leaves for a memorable experience(tearing each other's clothes off, pressing them firmly against a wall, etc). First I like to hear them moan and its just more fun to take part of. Maybe I'm just an aggressive guy by nature but I know girls must also love rough sex in the right moments.
