I don't hate gays. i just really don't understand why same- friends desire with each other. why?

when i was young i went with friends bar-hopping and we often went to gay bars because the people were not violent and they were entertaining. but i never really thought much about it. i know that the idea of me kissing another woman in a ual way is just not in my program. i have had many gay friends. we never talked about it and we were friends at work. i was not repulsed or aggrevated. but now i, must say, i just cannot fathom why. i could see cohabitation etc. opposite is necessary for most people. why is this small segment of the population the way they are. i guess nobody really knows. beats the hell out of me. some people wear big body tatoos. i would never do that. unthinkable. is it all some extreme form of rebellion and radical reaction to something. i have asked gay friends and they didn't know. i know my female gay friends were strongly atagonistic toward males. maybe some event triggers it. puzzling. as very dear friends is one thing. ual partners? no me.
