Should I have sex with him

Ok so I've known this dude for a long time. He keeps makin offers to have sex with me, and im thinkin about doin it because I want to. he thinks I dont know how to put I do. I just wanted to ask anyone if they know any positions I should try to make him...

f*ck me at his best.

doggy style but not in the as*s feels good, they can use your hips to hold while they keep going, ...im in the same situation there this guy whos just a friend and me and him discussed having sex, I want to aswell. but I also like him he knows that he just doesnt want a relstionship, but I'm looking for a good time lol

doggy style, let him or you undress each other give him those eyes to seduce unloosen his belt or let him unloosen yours to remove shirt pants and then just let him move in and out HUMP HUMP show your emotions to him.

well personally I like being on top of mo boyfriend and just like riding him like a beast...he always wants me to be ontop of him backwards so maby you want to try that...I also like it when my legs ane up on his sholders hehe ;p
