why do most guys leave girls after they have sex?

I agree with the answer above - girls who’ve done it tend to act as if a guy really owed her something REALLY big.

Try this: when you have sex, do something for the guy that he’ll never forget (since guys really do sneak off to other women for the sake of comparison) , let him have his way for a while then act as if you’re the dominant one: leave the guy, then hook up with another - if he says back that you’re a s*t when he spots you with your new man, say in front of everybody within earshot that he’s really a sex fiend and that you hooked up with the new one because he treats you fine.

The point here is to make the guy really feel guilty for what he did - and you kill two birds with one stone with this. On one hand (if you really like the guy), he’ll crawl up to you for forgiveness so that he can take you back in and stick with you permanently - otherwise, you can hook up with your new man if he is really recalcitrant - but make sure you do something that’ll really ruin his rep among the girls. Never get mad - get even.

Another note: this’ll only work when you have gotten to know the guy real well - know what makes a guy tick and you’ll be able to hit him where it hurts most, thereby reining him in to your arms…

If you don’t understand some points, just send me a message…

Some guys use girls for sex.

because the girls try to act clingy
