I want the feeling of my clitoris back

im 16 and a virgin girl. i started masturbating for the first time,i used a vibrating toothbrush on my clit, since i didn't wanna break my hymen. at first it great and i had to stop a few times because the  feeling was overwhelming. this been going on for an hour and it i was feeling good,until i took my last break. then when i put it on my clit again the feeling wasnt the same, it was less pleasurable than before. i thought it was the batteries so i changed them,and put it on my clit again but it still felt less pleasurable and i had a little numbness so i thought i had to give my vagina some time to rest . so i waited til the next day and i did it again and i felt the same unpleasurable feeling. so now it been almost a month and i still have the same feeling when i mastubate with the toothbrush.did i ruin my clitoris,my vagina . what should i do ,go to the doctor,then my mom will find out what i did. im confuse about what do to, i want the feeling of my clitoris back.  i dnt kno what 2 do. plz help.plz
