I have the exact opposite problem, I just can't go unless I'm very comfortable with the girl, so out of the 7 girls I've been with, I've only 'gone' with two of them, and I only got to that point because I was in a relationship with both of them (not at the same time, haha). I need to find a way to bust quicker. I think most of the reason is because of the condom, it's so hard to feel anything through that thing.
