Never too late
When I was younger, I used to meet up with older straight curious men all the time. They had wives and children and never thought anything of it. But the sex for them was so exciting and new and I let them do whatever they wanted with me at the time.. they started feeling comfortable and trusting with me that they let me try leading. After that, a couple guys just couldn't get enough of men and their bi side took over. Sometimes, you have to do what your heart tells you. Even I'm married now to my wife and I got kids.. doesn't mean I didn't enjoy my earlier years but I've moved past it and that's my choice. I still enjoy admiring a great shaft and balls and love showing myself off to other guys but I just won't act on it.
I would agree that men have been doing this for a very long time. Men in the military or navy from time immemorial. To label these guys is disingenuous. And many went on to marry and have a family. It was part of their growing up.
Its only more modern times that society and the church have condemned these activities. Yes, the wealthy and the church throughout history have been hypocritical on sex.
