A new way I look at things, love languages all that crap. Even basic human behavior. People are going to do what they want to really do. Right now obviously your wife does not think your needs are important. If your sex drive shut completely down and ED took over, she'd probably figure it's no big deal because it's not needed...
However, what I'm saying is we "share" things with those who we care about. I'm just having a hard time understanding, why your wife is UNWILLING to share sexual pleasure with you, even if its not HER thing.
It just seems really cold to think you should just go masturbate and the problem goes away.
