Yeah, being "hit on" is not talking romantically to someone. I'll refer you back to that article I wrote about Lack of Curiosity.
Hitting on someone is basically asking for a hook up.
And look, hooking up is fine if that's what both people want to do. It's basically mutual sex aid/trade, rather than paying for it.
But it's not love. It's not a relationship. It's like fast food snack vs a healthy meal.
There are also places to hook up. Like bars. Nobody goes to bars to find the guy of their dreams. That only happens in movies. You go because you're looking to get laid, you're out with/meeting friends or work associates, you've had a bad day and you need a drink and a minute before you go home, sometimes it's a business meeting, that sort of thing.
When you cold approach women, asking for a hook up, you should expect a lot of rejection. Even frogs will sing for hours, lightening bugs will put on light shows, birds of all sorts will put on elaborate displays. But buman men think one or two cheesy lines they didn't even think of themselves, but got off the internet should be more than enough effort. Or else they're being cheated of sex and love.
If sex is what you want, then buy it, make a trade for it (hook up), and be prepared to be rejected a lot. A lot a lot.
If you want love, then realize that love is organic and must be grown. Start learning how to grow love instrad of thinking it should come prepackaged.
