We are, however, going to help you handle this DIY hair care situation as safely as possible. When it comes to people with vaginas, there is some thought that it might provide protection against dirt entering the vagina, as well as against friction from exercise or sex, SELF previously reported. There is also the unproven theory that pubic hair carries pheromones that signal when you have reached reproductive maturity and, in turn, possibly help you attract a partner to reproduce with. Whether or not you decide to shave, wax, trim, or simply leave it be is entirely up to you. And, unlike getting a professional bikini wax or laser hair removal, shaving is something you can do from home. At the risk of stating the obvious, shaving involves dragging a sharp object across your skin.
