LMAO! Guys can be so dumb! You don't have to guess, you can ASK! Just say "do you like when I...". But don't assume that just becasue we like it rough sometimes we like it rough ALL the time.
I'm a girl and i love porn. Otherwise I wouldn't be here! My current bf gets embarrased by it so we don't look at any together. But I have done with previous bfs and it isa real turn on - seeing new things we'd like to try. But don't use porn instead of foreplay guys!
