I get why many gay guys find the idea of having sex with a guy who (at the very least) identifies as being straight. The problem however is that more often than not, the sex itself is frequently robotic and lacking in actual passion/interest.
In other words, it feels like they (the straight guy) are going through the motions without really enjoying it because quite often they're not. It's more difficult to mentality get into something you're not really vibing with as with these kinds of performers it shows in the work they do.
That said there are exceptions to this rule (with some content creators/performers being able to convey some level of enjoyment), but more often than not, the rule generally holds true.
