what would be your reaction when your BOYFRIEND toLd you HE is GAY???

I would wish him well, and be thankful that he had the courage to realize his sexuality and tell someone. I would offer to help him in any way I could (to tell his family, to find a boyfriend, to be happy with who he is, etc.). I can see that it might be difficult for a woman to find out that the man she is with is gay. But, imagine how difficult it is for the man to find out. I mean, I am assuming that you mean a man who is at an age where he has a girlfriend, and therefore believes himself to be straight when he gets together with her. Then, at some point in the relationship, he comes to the realization that he doesn't find women sexually attractive. At that point, he also realizes that he does find men sexually attractive. Now he has to worry about prejudice, but he knows he can't be happy pretending to be straight. That is a very difficult place for any human being to find themselves. He is really going to need support and love, now more than ever.
