Gaydar is massive. Almost every gay guy I know has/has had a Gaydar profile... In my experience great for hooking up and sex, even had a year long relationship out of it... Would highly reccomend it, but as always you have to be careful about weirdos and liars (pics of someone else or taken when Wham! were still together) If u always meet in a neutral place first u should be allright. There are a lot of hotties out there online!
