It’s important to tell girls that they do not need to be sexual in order to be loved and respected. And it’s equally important to tell girls that as human beings they have bodily autonomy and can do whatever they see fit to do with their own person.
If you give one of these messages and not the other then you’re giving the incomplete truth.
From the perspective of someone who grew up in and left a religious family, I feel it’s also important to tell girls sex and virginity isn’t the most precious/special/important thing you can give a man. There are so many more worthwhile and significant things women have to offer a man/their partners. Being raised in a religious muslim family where your virginity is meant to be kept for 1 man and 1 man only and treated like it’s some kind of gift offering is pretty gross and I feel like it can really mess up how young girls and women view their bodies and mess with their self worth. It could even be detrimental to a point where a woman may put her comfort second to a mans sexual desire because she’s taught that his need is more important which is bullshit.
Don’t pressure girls to have sex but also don’t shame girls for NOT having sex.
As long as she’s over 18 what she does isn’t of any consequence to anyone.
