Why won't My Erection End

I'm about 19 and I have a really big problem. I've got a great sex life with my girlfriend. We have lots of fun and she tells me that I please her; she does the same for me. But, there have been a few times after sex, even after I came, my dick will still remain hard. My girlfriend thinks this is great, since she can go on forever. But, sometimes it can last for several hours. I don't know what's going on with me. It doesn't hurt so much, but it is uncomfortable and embarrassing! How can I keep my penis from getting an endless erection?

Have you ever heard the expression “one man’s trash is another man’s treasure?” Well, I think that is what we are dealing with here. That, or “don’t kick the gift horse in the mouth.” I am not trying to make light of your situation, but if you are not experiencing any pain, you just may have the ability to hold an erection even after you have had an orgasm. This can happen, and with time and age, the period between your orgasm and next erection will be longer. If it hurts you, or you notice anything else, consult your physician. In the meantime, though, enjoy your good fortune. This is something most men would kill for, so don’t be embarrassed about it.
