Virginity, usefull or not? Options

Is there any magickal use in virginity? Or at least in females, considering the entire fuss religious traditions make over it?

I've been wondering about this for a while and I can't seem to find anything relevant to the question that isn't biased by our christian heritage. There's a good bit of magick centering around sex, but I'm reluctant because the opposite might be just as true. I'm loath to just have sex for shits and later discover a branch of magick that specifically asks for this!

Does anyone here know something about such a system? Or how the hymen virginity relates to energy? I vaguely recall one of the grimoirs asking for a female practitioner to also be a virgin.

I'd still call them virgins in a sense. But sexual activity on a magickal level can be considered "impure", thus many models of magick require purification or fasting to cleanse one's soul so that they may perform a ritual without "tainting" their work with impure thoughts. And some rituals do require sexual activity at that too. but t echniquely I think a virgin is anyone who has not had actual intercourse. One way to look at it for women is if they still have an intact hymen, which is basically skin that is broken when a virgin woman has sex the first time.
