Birth Control affecting my husband ?

I’ve recently gotten off the pill for about 3 months after being on it for 4 years, which I met my husband while on it, and I’ve noticed he’s a lot hornier than usual. Note that when I got off, he was 6 months into his deployment so when he came back, I wasn’t so surprised he wanted to right away. He’s always wanted to have sex at least once a day which I didn’t think much of because we didn’t always have sex everyday but now it seems like he wants to everyday and multiple times a day. I know usually getting of BC affects the woman but I felt normal, only thing to change was my period being shorter. It makes me feel like now that he knows I’m able to conceive, it some how is affecting him and makes him want to jump my bones every chance he can get (ex. like female cats in heat releasing hormones for male cats). Does anyone know if this is really a thing or is he just really horny lol?
