does his interest in sex seem over the top or is this typical of a guy's view of sex?
Sounds typical, compared to my view. Understand, however, that MY view is the view of a man who gets to ML a few times a year with his W. For example, last year, about four times.
Some things I was nodding my head to, as I was reading your message: "He said that he thinks about sex so often and he wants it so badly but feels like I not interested.... He said when he withdrawls, that's what he's thinking about. He said that he feels like he spends the weekends wondering when we can have sex, and he thinks I spend the weekend thinking how can I avoid sex. He said that he thinks I'm not interested. He said he tried the flowers thing and it still didnt' seem to make a diffence in bed." Yep.
