As a straight man, I did that with Tinder and made a number of friends, but they were always women. I never had any luck with guys I met on Tinder, not really sure why.
I mean, if I have a Tinder profile, I will expecting people who tapped me are all womans. So when I found out it's actually a guy, I will be surprised and feel wired.
I do have a friend that swears by couchsurfing.com[1] for finding new friends, but I personally haven't tried it.
