If he is able to be erect for ************, he should be able to be erect enough for your vagina. If he really can't get erect enough to satisfy you, he should see a doctor to find out what the problem is. Viagra or cialis should be able to stiffen him up enough. That stuff is expensive but you don't need him to take it every night. After all, he does have a tongue (and fingers) for the non-viagra nights.
You are right. He needs to get a very large clue. You are still a young woman (no, I mean seriously, I still think of myself as being a long way from over the hill and you are at the least five years younger than me) and you deserve both sex and love.
i think him being impotent, .. and never touching you are two different questions entirely.
