Well, certainly, but being married with kids does not make you straight. I know several gay men who were unhappy in their heterosexual marriage who later came out and felt much more happy and at peace. They continued to be involved in their children's lives, often in a more healthy and honest way.
It's individual.
Here's another perspective and some additional information on NARTH. I feel people should have all the facts:
http://www.truthwinsout.org/narth/NARTH, and many other organizations driven by a subset of religious beliefs, project many stereotypes onto gay men and gay life.
I have never been the type of gay guy who drinks cocktails, discusses their hair and prefers women as friends. I was really afraid to accept myself. I was terrified that I would be like the man in those old Saturday Night Live skits .. he accepts he's gay and then suddenly he has an embarassing lisp.
There's nothing wrong with more feminine gay men. However, to color all gay man as being 'deficient in masculine' is like calling all black people 'excessive in aggression and thuggishness'. It's BS. There are more than a few pro level athletes in ultra-masculine sports like football which are gay. All of the 'causative' factors suggested by NARTH and others are just narrow reductions. And the depictions of life as a gay person as being meaningless, full of hook ups and drug parties, they don't represent the better possibilities that are out there for gay people....
I simply feel that people should have access to balanced information about what being gay is like. Family is very important to me, and I have learned that being happily gay, committed and raising children is not only possible, it is increasingly what gay men are looking for.
So when I hear 'acting out' I think of people who are pushing yet more of themselves down where they don't have to see it.
SSA is a set of feelings. For some it is just the desire to GET WITH, FUCK, BE FUCKED by another man. For others it includes romance, cuddling, and close care. For others it means the lifelong commitment of partnership. For some it is wanted, for others it is not wanted. In my experience the best way to avoid unnecessary suffering is to witness my thoughts and feelings and to listen to my heart about which course to steer. I don't believe in a single 'gold standard' of action, so I won't try to tell you how to live a happy life.
But I certainly believe it's possible to live a happy and gay life!
I hope to be there one day. For now, I would like to learn what Love is, not in terms of gender, but in terms of unconditional love: to be truly cared about by another person and to care about them too. To me, that's what really matters.
