a good comparison, i see it similarly. for @Amira this is an important goal to stay chaste, so she should do what she thinks is necessary to achieve this goal. I don't think thighbands protect the hymen because @Amira doesn't wear them 24/7 for practical reasons, but I think she knows what she's doing.
PS: i don't think it has anything to do with whether she is muslim or not, she seems to behave very western, besides there are enough examples of christian girls here. we should stop linking this to religion
