I don't believe the game was designed to be a trainer. I.e. no matter how long you repeat and action, model won't start liking it. It is a genetic evolution game; your job is to rate accurately in hope that the next generation does what you want.I've been tactfully going at this girl's ass for 4 hours, and her Pain Gain Modifier is set to 0.01, yet I still can't put my cock head

Seems to be the most glaring issue of the game.

The game takes into consideration a lot of variables when computing the resulting 'pain' and 'rage'. Usually dozens of genes will contribute to a given result. The usual problem is penis size and hole size and depth. But it can also be your leg touching her thigh, etc.
So either just sluttify the girl and get your way, or just rate and send away.
