Iv'e heard about some girls bleeding from their virgina when they loose their virginity. From what iv'e gathered its some sort of seal that can break at any time, and not walways during sex, perhaps during a sports lesson or somthing. Anyway, my girlfriend says it hurts when we have sex, and we have had it since christmas. So i had a therory, what if her seal hasn't broken yet? what if i keep kinda pushing it (thus the pain) but not enough to break it? Although shes been having her periods for years, doesn't that mean that it mustave broken? otherwise the blood would pool inside? Im not sure on the details on this seal thing so couold someone enlighten me please.
