Is it bleeding a lot? Is she sure it is not her period that started early (having an orgasm close to her period dates can cause that). It can also be a micro tear in the vaginal wall, not her hymen - does she know for a fact that her hymen tore?
She should pat herself on the toilet, not wipe.
In general, when a woman bleed from something like this (not just random bleeding), it is often not very serious. If it does not stop, or it is very heavy, she might have to speak to a doctor.
Please encourage her to stay safe with her boyfriend.
