I am the same way. I have bi thoughts all the time. All I can think about some days is a nice cock to hold other than my own. I am happily married and have wanted to say something to her about it but believe it is best left alone. I didn't have those thoughts much when I was younger, but the older I get the more I think about it. I don't want the have sex with a man, but would love to stroke his cock. I know it would be a divorce and shunning of the people I love if I every acted out with someone and they found out.

Same situation here, exactly!!!! One first rule: don't feel obliged to talk about that with your wife. If you want to stay happy with your couple life. then keep that as your extra-private garden...You'd make more harm than anything else to confess, whatever the thrust can be (religion, moral, or whatsoever)..... I'm experiencing such a situation for years.....the only one to know is me....and some guys with whom I had som experiences.....I'm convinced this way of doing is much better, and much more harmless than any other. I've got a happy couple life, a happy private sex-life, and something about which nobody knows and will ever know. This allows me to manage my strong (and somewhat pervert ?) sex-drive without any unnecessary problem...

Take a look at my blog, "Defining Sexual Orientation". It should give you something to think about.

As both BushPilot and skone have said, you sound completely normal. It is not at all unusual for a person of one orientation to have dreams, desires, fantasies of the other. I'm as gay as they come and I often have heterosexual fantasies.

It sounds like you're at a point where you internally need to explore something differently sexually. You can either enjoy the turn on your getting out of this emotional and be safe (protect your marriage) or, you can find someone with similar interests and live out your fantasy. Either way, being straight and enjoying the male form are not incompatible, just confusing some times. It's normal though so don't worry about it.
