I was on grindr recently and saw the face of a coworker of mine on the grid. This coworker is pretty good looking so I wanted to see if it was actually him. The profile was only looking to talk and trade pics and on his profile said to not ask to talk on other apps. At this point I was suspicious as this seems like the m/o of a catfish. We traded face pics but he also sent some nudes without face. He didn’t seem to recognize me so I asked if he did. At this point he says “oh shit ya” and then says sorry and blocks me.

Keep in mind I assumed he was straight when I met him so my question to you all is should I talk to him about this either via dm or in person? because if it is a catfish I kinda feel bad and want to let him know what’s going on so that he is aware but part of me also wants to chance it if he actually is gay. Would appreciate any guidance.
