Alright look.
Females shouldn't give it up the first night because we'll file you as a hoe. Simple as that.
That said a lot of that "making you wait" bullshyt is....bullshyt. The OP is spot on. It makes the relationship about sex. Steve Harvey and other bytches don't understand this.
If the man going for the woman has any type of worth (i.e. has options) and is willing to wait HE CAN STILL SWITCH UP AFTER YOU fukk DUMBASSES. There are 4 types that wait.
1. The lame. He's well adjusted to life in the desert. What's another 90 days? He'll wait on you. But ironically these simps aint the type you choosing on in the first place. His place on the list is damn near fallacy.
2. The Playa. Most real nikkas fall in this catagory. Simply put, he'll stick it out only because he's gettin p*ssy somewhere else. Chicks underestimate how easy puttin in work is in this generation. I've sent text while getting head. I've sent texts while takin shyts. I've texted chicks while driving to another chick's place to fukk.
3. The Egoist. Regardless if his initial intention was a relationship or a smash and dash one day a horrible epihpany hits this nikka. He realized he dumped cash or a large amount of time on a woman and has absoultely nothing to show for it. You've hurt his ego. Now he will go through the motions with fueled with bitterness and the motivation of the fukkin Terminator just so he can smash and validate his spending and break your heart in the worst way. And it's your own fukkin fault for playing games.
And last but not least
4. The innocent brainwash victim. Females don't understand this, and probably neither do you nutless simps, but real nikkas know; your dikk has a mind of it's very own. And that muthafukka is POWERFUL like Professor Xavier. He may honestly think he likes you. And he sticks it out because he may think you're worth it. All of a sudden though once he busts a nut and Professor X is satisfied, it's over. He starts noticing your annoying ass laugh. He starts not being able to stand your conversations. You don't look as good as you did when you left him stranded in his own horny thoughts for 90 days. The shyttiness of your personality is no longer masked by the allure of new p*ssy so eventually you get dumped.
Honestly the best solution? Give up the p*ssy.

Not on the first night, but don't hang it over his head like a donkey with a carrot either. It makes the lame feel himself enough that he'll probably get whipped, the playa will leave, the egoist will never get hurt and the brainwash victim will be lifted and think with the head on his shoulders. Every girlfriend I've ever had I had sex with prior to dating.
Every chick who tried this garbage I've dipped out on. There will be chicks out there who aren't playing games. Chances are, if your personality ( or p*ssy for that matter) was worth a shyt, nikkas wouldn't dip out on you in the first place.
