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 guess that virginity would be of large value to someone working magick within a "christian" framework, as you can more easily relate to the dogmas thereof and potentially if those are in fact relevant the appropriate godforms. However, sex can certainly be a tool for the expansion of concioussness. I would speculate that the physical act of copulation is beneficial in balancing the male and female polarities in the energy bodies of both/all participants. Finally, I recommend finding a like minded partner, potentially being in a relationship with them, hence facilitating the acknowledgement of the sacredness of sex and the practice of such methods as i have alluded to.
