What are some sex tricks?

I want to know some things that will make things more interesting in bed. Any advice?

go rough....rougher than before

I guess I just like girls who like aggressive guys being assertive when it came to that stuff. Even biteing gets some people going.

If she's one of the girls who like romantic stuff light candles, and take it slow kinda like she's a virgin but not that slow just don't ram it in.

If she's one of those rough girls! Be assertive let her know who's in control just don't make it feel like she's bein raped or somethin ok.
