waiting until marriage

I (18F) had made a post (not on here but a sub to specifically ask men things) about saving yourself for marriage and most of them were acting like saving your virginity for marriage is stupid and how they would never date a girl who’s saving herself for marriage. So all of the replies were pretty much just filled with people saying really sexual things or calling me brainwashed by Christianity and saying that every guy is going to want sex in a relationship before marriage. And people mention sexual compatibility/how waiting until marriage is a bad idea.

So this is kinda bothering me. I'm afraid that a guy will want sex if I get in a relationship and i want to save myself for marriage.
