Hi BeyondBreaking,
I am so sorry this is causing you triggers, but I'm going to have to go against the flow here and say this isn't what you think it is.
I also play the GTA games and the strippers/prostitutes in these games are not alluring, arousing or attractive and they are not meant to be.
The GTA games are instead trying to be as politically INcorrect as they can be and they are highlighting the dark side of popular culture, sex workers and the drug/vice world in a dark comedy sort of way.
In the GTA, there are a number of "mini-games" that you play that are dark and full of irony, with the stripclub/VIP rooms and private dance being one of these sarcastic/ironic dark comedy mini-games.
If you look at the strippers, they are not meant to be attractive. They have the most bulbous, ugly, cantaloupe looking overdone implants, dark blue varicose veins, track marks, pimp stamps, ugly tattoos and overall druggie look. The "mini-game" aspect is to get their "LIKE" meter maxed, which is done by performing objectifying and insulting commentary to them while groping them. The "flirt" commentary is like "Keep telling me how handsome I am" or "silicon and desperation!" or comments on their "daddy issues" or other such degrading depravity. These things fill their "LIKE" meter (more irony). If you do this while a bouncer can see, you get thrown out and have to start all over so it IS like a game. Max out the stripper's "LIKE" meter and she invites you to her home (for sex), where you quickly pan to the next morning and now she is on your cell phone contact list, where you may call her any time from there for a health boost.
So that's it. It's a stupid, un-arousing, non-sexual "mini-game" that is designed to express an irony of sex workers in their depravity, pimped, drugged out, terrible plastic surgery, mental issues and the like.. and if you "win" the mini-game, you basically earn another easy way to give you full health when you get hurt in the game.
Lastly, not to spoil the game, but the stripclub is a necessity in GTA-V as it becomes a safehouse for one of the characters (safehouse is the place your character can rest/save your game, change clothes, and park cars you wish to keep). So having high "LIKE" meter and sleeping with multiple strippers is a quick way to replenish health from a quick dial on your cell-phone and/or visit.
Is the private dance/VIP/sex a 100% necessity? No, but visiting/using the stripclub is as it becomes a safehouse.
I seriously doubt your WH is getting any kind of sexual ya-yah's off the strippers or prostitutes in GTA as they aren't in the game that way. It's actually more a case of excessively degrading strippers & prostitutes and making them look fairly disgusting, unappealing and messed-up.
Sorry again as I can totally understand you seeing lapdances, private dances and sex in a videogame as being some form of porn/eroticism. But let me assure you, nothing could be further from erotic than the GTA games as the presentation is purely non-erotic, non-arousing and quite disgusting/degrading as a form of dark comedy against popular modern culture.
Lastly, I'd urge everyone to see Conan O'Brien's review of GTA-V. He also goes to the stripclub in-game (which leads to a LOT of hilarity) and showcases this (and other aspects) of the game:
