Can someone explain this to me?

I just don't get why so many girls come to the community asking when it's okay for them to have sex or if it was alright that they just lost their virginty at whatever age. We don't dictate how you live. We're not your parents/guardians. YOU decide what you do with your body because that's YOUR right. I may not always agree with a young teen having sex, mostly because they have the highest STD & unplanned pregnancy rates, but I can't stop you from it. You do what you want because you're an individual. Don't look for confirmation here because you're most likely just gonna get judgement. If you think you're ready for sex, fine. All I ask is that you make conscious decisions and are safe and educated in your actions.
