I have no idea ... I'm too triggered (flash backs of molestation) to be on top -- interested in the responses, though, as I hope to overcome this eventually (sooner rather than later, please?!)

I don't really like being on top cause it just doesn't do anything for me really, but I do it anyway cause I know that my BF likes it. Generally I think that guys like the visual they get from the girl being on top. I try to make myself feel as sexy as possible before doing it, and usually do a lot of foreplay to get him really excited first. Teasing him also makes him not last as long which is good for being on top IMO. When I'm actually on top of him I usually just try to act really into it, I usually take his hands and put them on my body to encourage him to touch me, like touching my breasts, arms, face, etc. Sometimes I lean down to start kissing him, or give him lots of eye contact, or talk dirty in his ear. It's really not that hard when you get into it. He seems to like it cause he always finishes that way. Sometimes I also kind of hover over him while I'm kissing him or kissing his neck and let him do the thrusting until he gets closer to finishing and then I'll finish him off by making him lay still and riding him. You can do a lot to make it fun for both of you, just be creative.
