Where I'm from, it's a pretty common saying that sex is for prestige and a wank is for joy. Of course, a relationship doesn't primarily consist of your stepsister getting stuck in the dryer, running a 10-man train on your loved one, or whatever else. Even kids aren't that stupid.
It can lead to issues with your thing not being attracted to people you don't find attractive, since you're not desperate, but the opposite is, in my opinion, worse. Many good men and women have fallen for dogshit relationships with mediocre sex out of fear of no sex(ual outlet).
