I am a married man, who thinks about sucking dicks. am i gay?

Yes, you are gay.

I'm also married & am very attracted to women.

But, just recently having the fantasy myself, I went to a local ABS & checked it out. Yes, I was very nervous since I've never even touched another mans cock

But when that first one came through the glory hole & I saw how large it was, I just had to touch it & feel it's girth.
Before you know it, I was licking the head & sucking it like my wife sucks me. I've since sucked six & will be sucking more.

I would say you have bi-sexual tendencies. No big deal. I think you should discuss this with your wife. Honesty is important. Let her know what is on your mind. She may suggest therapy. I don't know. On the other hand, she may tell you to bring someone home so she can watch. We'll hope for the latter.

It's ok to think about it. It's not ok to do it. Well.... Unless your wive is ok with it.

You are not gay - bi certainly.
If you have only fantasized about sucking cock you really should try it, having a guy cum in your mouth, swallowing his juice, it's all good. cheers

Yes, I would say you are at least Bi. Actually, nothing wrong about thinking about it but another level of problems if you actually do it.
One of the problems that I see is that if you like it when you do it, you will most likely think about it much of the time. (Even when having sex with you wife.)
You don't really want this unless you are willing to give up your married life.
You can live without fulfilling your desire. Just get it on the "back burner". You will have a much better life in all ways.
Good luck!

You wouldn't be the first guy to realize he was gay after a number of years married to a woman, especially at your age when it wasn't very accepted to be out of the closet when you married.
You've still got half your life left to become yourself and live openly. Just be kind to your spouse, as she may find it very hard to understand why her marriage is breaking up.
