my mom won't let me wear tampons or even ride a bike!?

My culture is big on women with ripped hymens. Men usually only marry a woman if she's never had sex before marriage.

Accidents happen on bikes where the hymen is broken, and tampons, I believe, also break it. Apparently, if her hymen is broken, the guy who wants to marry her will not know whether she had pre-marital sex or not, and so he just won't marry her, and neither will another guy marry her.

I understand my mom's reasoning but why does my culture have to be like this? Are people not educated on the fact that some women purposely or accidenty break their hymens and not through sex? So if a girl slips and breaks her hymen she will not get married because people will have no proof if she had pre marital sex or not? It's disgusting in my culture how if a girl is raped, aside from dealing with the mental impact that getting raped had on her and even the physical impacts, to make matters worse she now also has to worry if anyone will ever marry her. This is what she gets for getting raped? Even more issues to depress her?

This really annoys me. I've always wanted to ride a bike, and just wear a tampon. My flow is heavy and sometimes I have to wear two pads, and it's annoying. I can't wear leggings either since the (two) pads show through. Not to mention how the blood gets everywhere.. And for others it's even worse, like with the rape thing.

There's nothing to really improve my situation, since i understand my culture and its ignorance, but anyone have opinions on this?
