Ive only had sex on top with my current bf, so i dont know how other people do it. But my fav is just having him lay down and me sitting on him with my knees on the ground and slide forward and back (twards his head, than back to his feet) i put my hands where ever i feel is most comfrotable at the time, sometimes on his shoulders or on the ground, or just let them hang lol. occasionaly ill just move up and down... im not sure if that does much for him or not, but the first one is the only way i can orgasm while having sex so i like that the best lol.

You could always ask him what he likes, or as him what he wants you to do, thats how i found out about what my guy likes me to do on top, because i had no clue what to do lol

Hope i could help alittle

It all depends on the way he likes it. I can tell you what some of us don't like. Don't jump too hard you can hurt his balls. Some guys don't like hair in their face, personally I don't mind as long as my girlfriend does not move her head too much and her hair are not moving around my face too much.

Some guys love when girl kisses them in this position. It's also pleasurable because your body mass is spread around so it's not like all the mass at one point.
You can aways ask him to put his arms around your butt and guide you a little bit.
