Assumption over age

When I was 18 I was beating my stuff to girls who I believed at first glance were my age and older on YouTube and TikTok doing trend and sexually toned dances and stuff. Now I’m 20 and look back in hindsight and think that maybe it wasn’t a good idea, as some of those people were probably younger than I had given thought. I regret it deeply and while I understand I haven’t broken the law in any way as I’ve researched, I’m concerned that maybe people won’t like me anymore. (I put this under ST/SH, as I am kind of contemplating stuff rn as I’m losing my mind)
