I turned 30 two years ago. That is when I discovered sex was actually great.

My husband is 36. He enjoys making out and leading to the undressing but as soon as it comes time to get down to business, he is not....you know, hard. He says he is "in the mood" and can feel the tingly sensation but when he looks down it doesn't match. This is ongoing and it is sporadic.
He is embarrassed, I'm frustrated, he's upset. He's seeing the doctor later this month. Anyone's husband go through something similar?
