Hey Alice!
My old boyfriend and I used to have sex in three or four different positions, including sitting, me on top, doggie style, etc. My new boyfriend and I are a lot closer, and I have much better feelings for him than my old guy. Yet for some reason, we can only have sex in the missionary position, because I can't get him to go in me when I've tried to have sex on top. When we sit (me on top) it doesn't go in either. What could be the problem?
