Sex Drive Through the Roof

I just stopped breastfeeding last month and I think my hormones are all finally evening out, which is amazing. Between being pregnant and then BF for 9 months I had a low libido, and we only had sex 2-3 times a week, and not even that when I was really pregnant because I was so uncomfortable. I'd do some hand stuff or oral but it was just for his benefit, I really wasn't interested and I didn't even want him to play with me in return. Well NOW... I am so horny all of a sudden! We're having sex at least once and sometimes multiple times a day! We get done and 15 minutes later I'm raring to go again. I wasn't even this horny before I got pregnant, and my husband is smoking.

Has this happened to anyone else? I just can't get enough. I've never been like this before. I mean I'm not concerned, just surprised!
