TMI topic about orgasms!!

I'm 19 weeks pregnant and I seem to want to orgasm all the time. I'm self masterbating about 2/3 times a day and reaching orgasm and still having sex with my husband 3 times a week. I just seem to be obsessed with being turned on at the moment and as soon as I start thinking about it I HAVE to go masterbate. Anyone else really turned on in pregnancy?
