I don’t buy into the idea that boys not having experience talking to girls, or knowing how to build a relationship, is part of the problem. Girls certainly don’t need experience to figure out how to get male attention – it’s pretty instinctive.
It is instinctive, but we’ve trained ourselves to not do it. And it is an issue.
One prominent (female) family therapist told me that it is a very common issue that yeshivish girls don’t know to interact with guys in a romantic way. And the same with guys. Or perhaps more accurately, that they think it is inappropriate to, and they hold themselves back and a bit aloof.
Is that a problem? Depends what you think. If you think it is important to have romantic feelings about one another before you get engaged, then it is. If you don’t think so, then it is not a problem.
