Men in general doesnt really want to settle down.Mostly gay men.But,straight men are not far behind.Gay men are very sexual.You cant compare gay men to straight men.Unlike straight people,gay men were never encouraged to have a serious relationship and to be monogamous with men.Gay men were never told,someday you will get married to a man.So,unlike straight people,gay men never had pressure to be monogamous in the first place.So,gay men fucks lots of men.Gay men just have more options and opportunities.
Men in their 20s = men who only wants to have sex
Men in their 30s = men who mostly wants to have sex
Men in their 40s and older = men who wants to settle down
Of course,theres exceptions.But its mostly spot on.
Younger men wants to fuck,when they still can.Sex is becoming less and less important as men gets older.
Gay men can settle down.But,its most likely the minority.In other words,if you really want to find the man who will always want to be with you,it will be with an older man.Not a younger man.Since younger gay men are still in their sex years.Gay men wants to have sex as much as they can.Gay men knows that it will not last.Straight men have a different mentality than gay men.Straight men often settle down a bit earlier than gay men.Keep in mind that,when it comes to sex,straight men have less opportunities than gay men.
Its not surprising that so much gay men are in a open relationship.
