Re: Is this a guy thing?
Yes, this is normal. Guys sometimes don't communicate well because they believe the problem is not poor communication of problems (which can be solved), but genuine conflicts of interest (which only lead to bigger problems). When a problem seems unsolvable, alot of guys clam up and repress their feelings. We just try to deal.
Also, some guys (I have and sometimes do) converse by bouncing ideas off of others, having no attachment to the success of their ideas. To most women I know, this is demoralizing, as they will tend to be attached to their ideas, and when an idea is met with ANOTHER idea, it creates conflict.
I have no idea why a guy would not be interested in sexually satisfying his wife. That to me is basically inhuman, mean, manipulative, and evil, and a place where there is no room to compromise. Granted, you might need some wierd stuff that he isn't into, but that is about the only place where he gets a pass. In other words, I have no advise there.
