If she's a freak. Bring a condom.
If she's a whore dump her now, because you will catch something.
If she's a innocent little school girl; Cherish her cause if you do you'll turn her into a freak.
Also what I do is take it slow(Depends on girl), and don't say anything stupid like some people up here may lead you to believe.
Final most important thing is... Don't tell her you love her, because you won't mean it.
Your on a gaming forum asking for advice chances are your like 12 and don't know what love is.
