Does this happen to a lot of men after sex or is it just my boyfriend? After sex and ejaculation, he'll still be hard. He assures me it has nothing to do with the sex... it's just that it's ALWAYS hard. He gets annoyed by it, but I can't help but laugh and say "least it's better than the other way around" and he agrees but at the same time it still annoys him

Is it like this for other guys out there? If so, what's it mean? Should anything be checked out?

He's 19 by the way. I'm thinking maybe it has something to do with being young still.
