Masturbation problem.

Samantha • Hi, I am 23 years old and love music, drawing/sketching, and several other things. :)
So recently in the past few days, I decided to use my toothbrush on my g spot and areas near there. 😳 Well, I used the toothbrush on that area too much and now it stings and is sensitive down there, and at times it feels like I need to pee when I really don't. What do I do and what is going on? Any advice would be appreciated. I tried looking up a solution to my problem on the web, but couldn't find anything. 😣
