As a (former) Catholic (former) schoolgirl, I cry, "Cultural appropriation!" But I also say have right at it and have fun. For me, those memories aren't fond or exciting. As I've mentioned, however, there are two good things that have come from it from the sex standpoint. One can be summed up by a quote from John Waters (whoever he is), "I thank God I was raised Catholic, so sex will always be dirty." The other is sex ed class (which was euphemistically called something else, like "Family Health") where I associated sex with (and became obsessed with) having a man's sperm, a living part of him, swimming around in my body for days. It is still something that thrills me, especially when it's more than one guy; it makes me feel special and powerful.
BTW, do you wear glasses? For me, coming home, taking off my clothes and glasses, standing in front of the mirror naked filled me with thoughts of the possibilities. In my clothes I had no tits, no ass, but naked I had small tits, pubic hair, and pussy lips/clit that belied everything else.
