Nothing -wrong- with either of you. There is a natural sedative emitted into the bloodstream of a guy just after he ejaculates. He needs to learn to hold off on cumming so fast. The best way for him to keep from falling asleep right away is to sit up and/or go down on you or some other physical activity. He needs to do the -squeeze- method in order to learn how not to cum so quick.

Well we go down on each other before we do it.. And he still really tired... I went down on him once before we were getting rady to do it, he went, and then we had to wait like 2 hours to have sex cos he wanted to take a nap haha

This is how my boyfriend is.. It's upsetting sometimes. When I cum I don't need to take a nap. I just need to rest for a few seconds.. So it's hard to understand him being so tired sometimes.

That's because your a girl and he's a guy - it's all in the hormones.
