Point out in any of my posts where I said to have sex with every person you date? Because I never said that. You seem to have a very naive, black-and-white view of sex. It's either people are completely chaste, or they're running up a tally of sex partners in the triple digits. There doesn't seem to be a middle ground to you. Every post I've made has referenced LONG-TERM relationships. As in, you've been with the person for a while. Not jumping into bed on the first date.
Also, the fact that you think I meant "porn star" moves kinda proves my point. You have a fundamental lack of understanding about what sex is. When I say "sexual compatibility", I don't mean "rock her world like a bouncy castle inside an earthquake". I, and others in this thread, have explained that it means that you two have compatible desires towards sex. That means comparable sex drives, comparable opinions on sex, and just an overall sense of chemistry. Chemistry is difficult to explain. It's the feeling that what is happening is "right". And you don't get that feeling until you do it. Or you do it, and you find out there's no chemistry whatsoever. Some of this you can discuss beforehand. But a big part of it is learning about each other during the act. No, by no means am I saying that you have to do any of this. If you want to save it until marriage, that's entirely your choice. All the power to you. But I will say that your posts here reveal a lack of basic understanding of the emotional impacts of sex. Yes, promiscuity can cause negative emotional effects too. But so can a poor sex life in a committed relationship. In this area, what you're looking for is a healthy, balanced relationship. To simply say "everything will work out fine once we're married" is kinda naive. Sure, it DOES work. A lot of times it does. But it absolutely isn't a guarantee.
