What the hell?! Do you realize what Monkey can do? Ignore all these restrictions and add “wishful thinking.” But even so, it doesn't work. What's the point of all this if you can't do anything right even with cheats. It's bullshit.
I never had problems with penetration aside from the limp dick bug and i played most of the game without Monkey. I just noticed the beginner girls are mostly used to rate them and send them to other studios to make money, cuz without cheats is really hard to even have sex with them without shooting out the anger and fear meters.
Also another thing to notice, even when using monkey is the size of the dick and dick stifness. If the dick is too thick it will be harder to penetrate, and if the stiffness is too low it will also be harder to penetrate. I noticed that by defaut the stifness is low so increasing that in monkey might help. I use the stiffness in the middle.
Also using the hand to grab the player penis makes penetrating more tight holes easier.
So as long you dont play with a tree trunk that acts like a wet noodle, it should be ok. Getting BJs is still a challenge if its not a hired girl you already "trained".
