A good question. Perhaps as they age, they permit themselves to be more honest about thoughts that previously had been submerged and shoved away. My opinion is that very few males are strictly hetero. Most of us are a mixture. I started sensing this in my 20's, just a bit. It increased over time. By the time my wife had cheated on me and was only giving very poor sex, I was FULLY interest in young guys, so went to gay bars on business trips, and found young men that would let me touch them and grope them a bit, safely, for a tip. I was content with this for a while. Then one of them followed me back to my hotel room and gave me the hottest sex of my life and I was hooked. That was many bottoms ago. As someone else said, it feels natural for me to bond with females, but for mutually enjoyable sex, guys rule. I love pleasing young men. Everyone needs a hobby, right? (Sorry if I answered this thread once before.)
