There is a lot of types of gay. When I was younger I thought gay was just same sex orientation. There are people who exclusively have sex with people of the same gender, But the nature of casual sex is that many women just hook up with gay men because they can dispose of them later. Women really do hold the power in every relationship. 

 Women also have a phase of life called menopause, Where they are sexually disinterested in even the father of their children. Men don’t have this really. Lesbian relationships seem to be less about sex and more about partnership and companionship while gay men tend to be sex obsessed or oversexed. Often you find gay men are trying to prove to their partners that they are exclusive in some last desperate grasp for proof of self control, But it is just a different role in sexuality. Try not to think too much about it, But these seem to be the things lingering in the back of old peoples minds. Being young and naive seems to be the only time love is real, And ultimately it is a psychological concept like everything else.
