Some older fellows

Nothing creeepy about that, shes of legal age.

How does denying their attraction to some women make them gay? The only thing that makes a man gay is being exclusively sexually attracted to other men.

I strongly suspect that what you've observed is some guys covering their jealousy in more socially acceptable garb.

If you want to get all Freudian about this, it's possible that what's actually going on is that at least some of those guys are covertly sexually attracted to their daughters, and this means they feel a need to loudly protest that no guy their age should be interested in a woman that young. It's kinda like how it's a proven fact that the noisiest homophobic guys tend to be sexually attracted to men; part of their denial mechanism is being very loud about how disgusting gay guys are.

It is a large age gap and I have to wonder just how much a guy of 40 and a woman of 18 have in common. But really, that's their business. People who get all judgmental about other people's relationships when the people in question appear to be happy together need to get a freaking life.

It depends what they're saying. I question why on earth a 40 year old would be in a relationship with an 18 year old. She is basically a child compared to him, and these kinds of relationships do sometimes occur when the older person wants to have control over their partner, so they choose someone who isn't on their level. Nobody their own age wants to be with them. However, this isn't always the case.

From what you have said if sounds as if they are mostly focusing on the physical side of things, which does seem a bit sus. Youth is generally considered to be attractive. 18 is an adult. All of my concerns around big age gap relationships are focused on maturity and life experiences. It has sweet fuck all to do with physical appearance. Young adults tend to look fantastic. It's just how humans work. It's very odd that they are pretending she isn't attractive. It seems as though they have entirely missed the point. Be cautious of them.

That guy is kinda creepy.

While it may not be the accepted norm, as long as its not their daughters, who really cares who is with who, every one of us has the right to be happy.

Not creepy. He's obviously got game.

I'm an older man (mid 60's) - and what I find creepy is the comments of the other older men.

I also think that Boojum is likely correct as to the reason.

It's only creepy if the guy knew her before she turned 18.
