My boyfriend and I have fantastic sex. I usually cum 8-10 times each time, and I can tell he's enjoying it, but he never climaxes! I ask him if he has and he says "I don't know." That usually means no. Am I doing something wrong? When we met, he was a virgin and I was not. I have been trying to educate him, but I really don't know a whole lot myself, I mean I know enough, but I wonder if maybe he just has way too much stamina for me of if I'm doing something wrong. Any pointers on how to help it along?
