So, the female version of the simp is the slut, not the pick-me. This is because women are the gatekeepers of sex while men are the gatekeepers of relationships/commitment. Simps give their attention/affection/commitment away for cheap or free, while sluts give away sex for cheap or free. The way relationships are supposed to work is that the man is supposed to remain attractive enough that his woman wants to have sex with him, while she puts enough effort into the relationship for him to want to continue to commit his resources to her.
This is effectively the old school Red Pill concept of "Alpha" behaviors and "Beta" behaviors, or better stated, Attractive behaviors and Comfort behaviors, or as hoe_math calls them Bad Boy and Good Boy. The key for men is having both behaviors. And Attractive is the split of Rule 1 - Be Attractive, in other words don't be fat, look after your hygine, get reasonably fit, dress well and Rule 2 - Don't Be Unattractive, don't be needy, don't be validation seeking, etc. and is the key to being fuckable.
At the end of the day, while a man has to be fuckable, a woman has to demonstrate that she's more than just fuckable, and brothers let me tell you, it's bleak out there.
