Is seducing "straight" guys actually a thing?

I'm not sure how to how to ask this, so I'm going to get straight to the point.Apparently there's a phenomenon in the gay community where lots of "gay" guys manage to somehow seduce "straight" guys; like manage to give them bj's or even get them to sleep with them on the down low.How, what, why...what?I'm not sure if I'm just naive, or if I have legitimate reason to be confused, but I'm really kinda stumped. My guess is that either the gay guy who gets the straight guy to sleep with him makes sure he is really drunk, OR, the "straight" guy in question is really bi/gay and doesn't really know it, or is just experimenting. OR the gay guy is just lying...I know we shouldn't really care about labels or who sleeps with who. I guess I'm just sorta shocked by the fact some guys can get "straight" guys so easily and casually because for me, I can barely get the courage to ask out the openly gay cute guys I see on hook-up apps/bars/around, not to mention ever working up the nerve to try to go up to a straight football player and be like "hey I can make you feel good" (my sad attempt at flirting)I think I would just get punched in the face....
