I don't normally insert myself in games. The product have to be really good where I start to insert myself without me knowing. a.k.a Immersive. And adult games don't do this for most.
I play any adult game if like how the characters look male or female PC. And if the Female PC is good looking then I know that I will see more stuff with this character design. So I tend to play more Female PC games only fraction more than Male. More than the what my PC will be I see the game engine. Each engine decide how I will play the game. I am also open to most engines.
I have tried Futa, Lesbian, Gay PC and didn't find them arousing

, so I don't play them.
I tried Guro and was not aroused and confused

, So I don't play them.
I tried Scat ..... Nope

, So I don't play them.
And know a little bit of crazy....

And I will admit that everyone inserts themselves even if they didn't actively thought of it. Any decision in game is a self insert moment Sub consciously ( this for those who say they don't role play, obviously for people who Roleplay they have their reasoning).
So from that and some after thought as I write this I have had an epiphany

that
I don't play Male PC a lot because IRL I am antisocial and have yet to make friends so getting close to female is even impossible, I have no idea what it will be like to get laid and when I do play Male PC my sub conscious tells me that's not happening to you mate! and now I am hard and sad....... and then just sad.
but when I play Female PC thats complete Fantasy

So my brain says yep many people will want to be with that ! Even me ! and more open to porn plots: need more magic lets fuck.

Ok. Don't want it.... Force

.
More proof...
When I am more active in real life (rare) I play more variety of games and when I am being lazy (default state) I play Female PC and boy when I am in real dark space I play NTR
