slut shamed for this app?

I just got slut shamed after I put something up about this app on social media because of all the sex advice on here. I have to say It did embarrasse me a bit but ultimately I just felt bad about the girls that were trashing me because I feel like they think it's wrong for women to publicly be open about sex and periods. Honestly I feel more confident about myself than ever because I'm embracing my sexuality.  Us women are hot! Why should society tell us to hide that part of ourselves?
