Sticking things up there

Okay so I'm a virgin - never had sex.  And I felt like sticking something in me tonight while watching porn - and it went pretty far in! It was the end of a makeup brush but I did put hand sanitizer on before hand. I am a little sore now but I just want to make sure that it was okay to stick something up there when I haven't had sex?? It didn't really hurt at first but it just kept going in and then hurt a little.... Is this okay?
