Why can't I find platonic gay friends online?

As a gay male who is settled and happy in a 20-year monogamous relationship, the thought of “socializing” with other gay friends has occurred to me, albeit online, but it has been like pulling teeth to enter any given chat rooms, especially gay ones. I soon discovered that 99.9% of chatters ONLY seek sex and the least they are interested in is friendship. I know that such platonic friendship between gays are possible as I’ve had several throughout the years, but lost those friendships as a result of them passing on through serious illnesses. There never was a sexual attraction amongst each other as we were just that… FRIENDS! I just wish I could find that again!
