I have been reading a few blogs recently of guys in a similar position to myself (married with families yet with a desire to be a with a man). Unlike me, they are taking very different routes in their lives. They have taken the step to come out to their wives and to reassess their lives together and to make a decision whether to live openly as a gay man or to remain married and suppress their feelings towards men.
I was aware of my attraction to men long before I got married but always knew that i would leave a regular life. Many people would say that I'm living a lie and I'm not true to myself but I just don't feel that at all. I have never felt a need to come out to my wife or to change the way I live in any way. Sure my life isn't simple and many people would find it difficult to understand how I live the way I do, let alone actually live that way. But it's my choice and as weird as it seems I'm very happy with the way I live my life.
The most important thing for people in my situation is to be happy (the pills help) and to enjoy your life and do what makes you happy without hurting anyone else.
