I'm a girl and i used a hairbrush (a goody brush) to masturbate with for the first time and it was really uncomfortable so I didn't go through with it. I washed it before and after I used it, but now I'm worried that the chemicals on the brush can hurt me because i gave it direct access to my bloodstream. I've never done this before and I don't want to do it again. I'm having some abdominal pain as well. Am I just over thinking this?
