My wife and I have not discussed the possibilty or erotic nature of guy/guy action but I have to admit, it interests me. I'm 46 years old and have been straight my whole life. I don't know what has changed (I'm not that introspective!) But something inside me is different. I'm willing to explore these new feelings and have discussed my changing feelings with my wife. She is supportive and always has been.
I say If it feels good do it. If you want to try it, try it. If you don't want to try it, that's your choice.
Just remember, all people are different and have a right to fell and experience without prejudice.
