My experience is that it didn’t make much difference, if girls ever talked about it they didn’t do so when boys were around. In any case most girls wouldn’t go out with boys from their own class. Boys on the other hand did exhibit an unhealthy interest on the rarer occasions that girls were caned. Girls would suddenly find that boys were interested in them after a caning, but quickly worked out that the interest was in details of the caning, rather than the girl herself and wouldn’t talk about it.
I don’t think you could gain brownie points by being caned, but you could lose them.
