This is a question that I get a lot.
You meet a girl. You sleep with her. From that point, should you start a relationship (as she wants) or simply keep it as a ONS?
It depends on a case to case basis.
You see, there are some people with whom you can spend only a few minutes at a time before wanting to kick them in the mouth. And there are folks with whom you can spend days in the same room and not feel bored or overwhelmed.
The same principle comes down to a woman. If you feel like she is girlfriend material and you can spend quality time with her, go for it. If you feel like the only good thing you’ve got out of the interaction was sex, then keep it for sex.
Don’t go through the pretense of a relationship just in order to get sex. It is not worth it. There are more than enough girls out there and you don’t have to settle with anyone unless this is what you really, really, REALLY want.
In order for a girl to sleep with you, she must meet certain standards. These differ from person to person. But in order for her to have a relationship with you, she must meet other standards, far higher.
Now don’t get me wrong. She won’t think this way. Nine out of ten girls, after sex, will want a relationship. It is something evolutionary, a part of her will always want to stick around after sex. But sex is NOT, I repeat, is NOT, the buying price into a relationship.
Always judge a girl but who she is, not if she sleeps with you or not, when going for a relationship. It will save you a lot of hassle in the long term.
