Cumming!

Haley • I am 21 years of age, I have a beautiful 2 year old daughter, and an amazing fiancé!
I can only cum/orgasm by clitoral. I have to be on top and he has to play with my nips or my anal. I really wanna know how to vaginal cum. My friends always talk about it but I don't think I've ever done it. Curios on how to do it? Any suggestions?
