Heres some ideas:
1. My girlfriend likes me standing and I hold her in the air while I fuck her. Fun position but I dont really hear about a lot of people trying it.
2. Try laying on your stomach and having him lay on your back and fuck you, kind of like doggy style but laying down. When I do this I balance all my weight on my dick so I'm pretty much balancing with all my weight pushing in her (think superman), then my girlfriend moves her hips and fucks me while I push it in her, usually pretty fun but use lube so you dont break the condom.
3. Another fun game I played with an old girlfriend is one of you lay down and then the other one gives you an orgasm, the change places, and keep giving each other orgasms different ways...kept me and her busy for a couple of hours.
4. Try playing with his ass when you give him head, dont ask him cause he might say its gay, just do it so he feels the good before he can think its bad.
5. Let him tie you up, blindfold and gag you, then tell him to do whatever he wants, you get some freaky sex, and he has to have all the ideas.
6. My personal fav. lay on your back on the edge of the bed and put your legs up like your gonna put them behind your head, then have him stand and fuck you. Try legs together or spread apart, usually the way I can get the deepest penetration.
7. Have him lay on his back then you get on like your gonna be on top, but then lay down and have him play with your ass while you ride him with all you got. Have him like grab your ass between the cheeks and hold you while you ride him. (Once like this my girlfriend rode me, and my bed, across the room, good times)
8. Go to sleep naked and have him fuck you.
9. Watch prono while you act it out with all their postions. Find one that really turns you or him on, what could be better than watching it and feeling it.
10. Or just get stoned and lay around with his dick in you and just make the little muscle movements, always good stoned fun.

Hope some of these ideas help you, or anyone else, have a good time smokin and fuckin :rasta:
