Not necessarily, no. There's plenty of people who have fantasies about and play games where they get raped. They don't, however want that to actually happen to them. There's a pretty big barrier between fiction/fantasy and reality. People may be more likely to gravitate toward their IRL fetishes in games, but they are also able to pick things in games that actively turn them off IRL.
IRL, I can't get with anyone who looks too young. People in their early 20's can sometimes come off as kids to me, and my boner nopes the fuck out of there. Even if their bodies are the sexiest things around, too much baby face kills the dong. Now, in game? Doesn't matter a bit. Hell, the game could describe them as a loli and it wouldn't matter. Why? Because my brain and boner are in fantasy mode, and the normal rules don't apply. Same thing goes for rape, which is something super relevant to TiTS and CoC. The idea of rape disgusts me IRL, and is something I not only wouldn't do, but something my ability to maintain an erection wouldn't permit. I'd get turned off and shut down. In game, however, I have no issue with being a max corruption serial rapist.
Now, that all aside, preferences you have in life CAN influence your choices in game, just not the other way around. I prefer dark skinned people irl, and that shows with my choices in games and what characters I gravitate towards. I like people with large appetites irl and tend to surround myself with those sorts in games. I... I made the mistake of bringing up appetites and just realized that I need to order groceries before the supermarket's cutoff time. If I wait too long they won't deliver until tomorrow and I NEED gouda for what I intend to make tonight. I think I got across what I was trying to say, so have a nice day.
