All men worry about this. Even my LDH who gets nothing but encouragement and positive reinforcement has wondered about this. I have to agree with SC on the "hardness" issue. My H doesn't have any "problems" getting or staying hard (this is one of the things that confuses me) in fact he's one of those guys who can stay pretty hard for a little while after he orgasms (quite convenient) but because I have certain insecurities due to my current relationship, I would need some reassurance that it wasn't my fault if I was involved with a guy with erection difficulties.
