Justaguy,
My story is almost exactly like yours. I have known that I was gay since I was 15, I am now 38, and hid it the same as you did for the same reasons. I was always the "good son", my parents, my father especially, was very conservative. I was expected to marry, have children and be a good husband. I did all these things, going through 3 marriages, all ending because I wasn't really into being with a woman. I finally came out about 5 years ago, to my 3rd wife. Of course that was the end of that one. Since then, I have come out to my family, but too late for my parents as they passed on before I could tell them. It father probably wouldn't have accepted it, but I like to believe my mother would have. I have come out to childhood friends and some co-worker, but must still be careful since I am in the U.S. military. Ours is not as accepting as other countries. My first gay experiences were not the best, mainly one-night stands, but since then I have been more careful about who I date. I have come out to some military friends, but I am careful about who. Only those I trust to be discreet about it. I still need to be careful, but will be retiring in a year and want to be an advocate for gays in the military. Sorry to ramble, but I hope this helps you.
