I don’t know that gay men have more partners, I think men in general are more apt to have anonymous sex gay or normal.
There is an abundance of research beginning at least with Masters and Johnson explicating the huge difference in promiscuity between homosexual and heterosexual men. The data are consistent and astounding. If you wish your comments to earn any respect at all, please do not waste our time with profoundly ignorant guesses. Thank you.
You’ve never heard the term “tea room” or “gay bathouse”? When I lived in SF’s SOMAR distict in the mid 80’s, there was a parking lot next alley over that every weekend hosted 10-20 gays against the board fence performing oral sex while a row of cars with 12v spotlights trained on the scene watched like some demented drive-in movie. This could be seen from many houses surrounding the lot. Neighbors with families who illuminated the parking lot with yard lights mounted on their houses had their car windows broken, homes vandalized or suffered phone harassment. Eventually the lot owner was forced to install flood light illumination and the problem moved elsewhere. Anonymous public sex is a core gay institution.
