I am so sorry!!! Now, with this extra info., i see why you feel as you do. 700 friends? On Facebook? That is rediculous! The thing that gets me the most, he is sending pictures of his member to others on the internet? I'm not sure thats even legal on Facebook, is it? I don't see how you could trust this guy? He certainly isn't putting much into his relationship with you, is he?
What, if anything, has he done about the premature ejackulation? If its as bad as you claim, he probably has done nothing? If that is the case, i suggest counselling. If, and i suppose thats a big IF, he is willing to go to counselling with you?
In one statement you say, "This is my second marriage, and i don't know if its worth saving"? Then you come back with, "I don't want to give up on my marriage, also don't want to look like a fool". Which is it? Give up, or stay and fight? YOU have to make up your own mind. You need to talk to someone, a professional, one who knows about relationships. I hope Dr. Becker-Phelps finds this one, she can help you!!!!! Better yet, you go find her. She is often on this site, but i think she visits "Relationships and Coping" community more often? Please find her, and ask her for help, she can, and will help you! She has helped me tremendously!!! Her name is Dr. Leslie Becker-Phelps, she has her own site, look at the right of the Relationships and coping page, you may have to click on one of the topics to see her, i am not sure right now?
I hope you find the Doctor! Best wishes!!!
