hi:) im 13 and ive never masturbated. i tried putting my fingers "up there" but i was scared so i stopped. for a while, ive noticed when i have a full bladder it feels good to press down on it over and over. and it feels really good. then i noticed its been stinging (tingely feeling) when i pee. my doctor said i dont have a uti and she put me on a pill for a yeast infection but it still feels funny. did i damage something?? im trying to stop doing this. im scared:(
