How do gay people get into a relationship without gay bars / gay dating apps?? Do they just randomly ask people if they're gay or what?

From what my understanding is, is that they kind of just know.

Yes, now all those pesky Questions about Sexual preference can be answered with a single scan from this marvelous device.

How about just communicating with fellow human beings. Engage in conversation. Plus there must be some dating sites . . . If I was single again I would most likely use a dating site . . . Why not.

Recently heard an interview on CBC Radio. Seems there's a lot of hook -ups going on in public washrooms.  ( not the most romantic enviro )

Also, there's a whole host of dating sites geared to them.

I didn't meet my boyfriend from a dating site or from randomly asking; I met him because a straight friend of mine told me they knew him and told me about him, then I later made the effort to get to know him. Sometimes you find other gay guys from networking like that, sometimes someone gives off a "gay vibe" and you risk embarrassing yourself if you're wrong, etc. There are ways of meeting us :)

It's obvious

If you at least know somewhat that person

The same as everyone .... Mutual friends, chance meetings at parties, etc.  People know when they are attracted to one another.
