I know a few. I work in a "creative" field, so gays just come with the territory. My boss, for one, has been with his partner for 20-some years.
Yes but how many on the side have they had. There is no such thing as a monogamous sodomite. They are either promiscuous, celibate, or dying.
I, too, work in a "creative" field and get a tad weary, like a lot of others, of having it so consistently be associated with homosexuals more than anything actually creative and academic.
About your boss and that "20 year" relationship, most homosexuals I've heard of and from and about maintain time-spanning habits with another primary "partner" BECAUSE they engage in multiple other relationships, both mutually and individually. They just establish property and routines shared with another compatible person but they make that possible because of the additional persons they have contact with as an acceptable practice of that primary relationship.
This article is so accurate and candid that it does define accurately just what the motivation is for homosexuals. The long/er standing relationships between two people is never similar to what you or I or other heterosexuals accept and know as "a committed relationship with the opposite sex" that continues through to and concludes through marriage for life. Homosexuals don't replicate that, they have an entirely different practice of "commitment" that they both seek and desire.
I work in a creative field as well. I know many gay men and some seem to be in monogamous relationships - although who knows. What is depressing is the large amount of gay men I know - many of them intelligent, talented people - who despite their advanced years still party too hard, take drugs and overdo the alcohol, fret about greying hair and extra pounds, and keep hoping to meet that hairless blond 17 year old boy.
