Tips on seducing a male friend?

In general, a confident, direct approach works well.

you free friday night?
"yeah"
Cool, I was thinking about getting laid, wanna join me?

(it worked on me)

Well I had one girl just come up to me and say she wants to rape me kinda freaky but I got the idea lol

Direct is always nice. To have a hot or even average looking girl, come up and whisper in my ear that she wants to take me somewhere and ride me like she owned me, would practically pop an instant boner in my pants. Ha. You can also just talk sweet to him and takes a good indication that you are interested and possibly want more.

don't tell him just do it lol
