So I'm about to be 18 in a couple months and I've recently bought(with my own money I worked for) my first thong. I went for my first time to Victory secret with my friends and I had fun and I was pretty proud of what I had bought. But when I got home and my mom saw she started calling me nasty and disgusting and saying "who u trying to impress with this?"  But when I tried to say how it was just for me and how no one was gonna see it and it looked pretty and made me feel pretty too, she didn't listen. So now I want to buy more but I don't want to be called nasty again. So what do I do?
