Male Homosexuals(MSM), are defined by who they like to have sex with, NOT by who they love.
That is not to say that they are not capable of love.

"Love" is hard to define most couples are "loving" some days, "hating" some days, "mildly irritating" MOST days :0) Couples stay together chiefly to raise their family in doing so they develop a deep emotional bond, they become comfortable with one another.

The bond, and the fact that their actions affect their extended family keeps most of the men monogamous....I think most women with children are naturally less disposed to promiscuity than men.

Heterosexual marriage is an excellent template for society, but the prevalence of "open relationships" amongst the male homosexual community, is extremely risky and unhealthy in todays sexual climate.
