In a calculus class I once took there was a young man. I don’t know whether or not he was a “yeshiva bochur,” but he wore a yarmulke and tzitzis. Every time he had difficulty grasping an easy concept, I would just shake my head and think “and they think girls are too stupid to learn gemorah!”
Now imagine if I was some BY girl fresh out of seminary and this is my first exposure to a frum boy who isn’t related to me. What a turn-off.
I think AZOLIS was right when he mentioned that there are those who say it’s better after marriage.
