Mari: So wierd, I have had very similar experiences to what you were describing! I can only come if I'm facedown on my stomach-- I don't know why, I guess its just the way I'm wired. Took me a hell of a long time to figure that out though. Also, if I'm really really turned on, I've been able to make myself come in under a minute. Only through masturbation though-- with other people it usually takes a good long while!

My advice would be to keep experimenting by yourself and also maybe to invest in some good quality porn *blushes*. I was totally embarrassed at first when I found it turned me on, but after I accepted the fact and moved on, wow-- was I happy! I think it's hard for a lot of females to admit that they find porn arousing; I know it was difficult for me. Try a few out and see what you like. 90% of having an orgasm is mental in my opinion.
