First of all, 90% of Tinder users are guys pretending to be girls. And people don't usually use it for the regular hook-up app it really is. It's never safe to use your face if you're a girl planning to send nudes later, or in your case, a queer. It's my advise to have a kik account beside your Tinder, post some photos covering your face, and if someone interests you, and agrees to verification (live photo on kik), you can proceed. Now, this person, if he is what he claims, he will definitely understand your suspicious and worry, but if he's not real, or someone tries to mess around with bad intention, he will probably say that he's offended you need verification from him, in this case, you can tell him to fuck off.
