Is it normal that i masturbate from 4-8 times every day?

I am an 18 yr old woman from california.
So every day for the passed 3 months after I lost my virginity in a sex orgy. I have been masturbating at least 4 times and sometimes up to 12 times a day. So about 4-8 times a day. And since I have lost my virginity I have masturbated every single day. Sometimes when I am alone, I try to pleasure myself. Or whenever I get the chance where no one will notice. I masturbate while driving, in the theatres, on my hikes, at my friends house, at the school library, any time I can get my hands under my clothes. Sometimes I even go to the bathroom while at work just to touch myself. I just can't help it, I love sexual pleasure. Like sometimes I will stuff a vibrator up my vagina and keep it in there for hours on high while I do w/e. I even have vibrators in my purse and my glove compartment. I usually am using the vibrator when I'm driving. Oh it just feels wonderful when I am doing nothing. One time I got pulled over with the vib in my vag. The guy came up as usual, I unbuttoned the top two buttons and dragged my skirt up. And i was blusshing super hard because of the vib and I put my panties on the passenger seat.. see I even like talking sexy, it turns me on. Anyways, I got let go, but I was cumming so much. The thrill of vibing while talking to a police guy was erotic. Well, I would like to hear your thoughts on my masturbation issues. Some people told me that's bad, but I can't help it, I'm in love with my hands and body. Well, is it normal that I masturbate a lot every single day?
