Why do older gay men want younger gay men as a partner?

Some older gay men want to be a 'father' type to these young guys. Also most young guys can last longer during sex and some older men feel satisfied when they can provide pleasure for young 'virgins'.

Because they are weird enough as it is...but no older gay man who has a brain wants to be labeled as a homophile (phedophile+homosexual)

Some older men and women(cougars), straight as well as homosexual, like younger partners to help them feel younger, make it feel like more of an accomplishment that they got into a relationship with them.
