It's hard to say. Personally, I've learned a bit which has helped reduce the stress on me and my wife. That reduced stress has resulted in an increase in intimacy over time.
Has it been frustrating? Yes. Am I satisfied? No. Am I able to deal with it better? Yes. Has this site helped? Yes. I've been able to trade war stories and learn from a female's perspective through discussions on the board.
I think without intensive couples counseling with a certified and well trained professional most will find it tough to make any major breakthroughs.
So, I'll still be here awhile as a slow steady improvement is better than nothing. I wish there was a magic pill to make everyone's relationships better overnight, but for most it's just one long, hard trudge without any guarantees of success.
Just my opinion and I'm glad you asked the question.
