Horny after miscarriage

So I had a miscarriage about three and half months ago. I’ve never really been a sexual being but after that time I’ve been really horny. My husband is hot but sometimes I just want hot dirty rough sex and he doesn’t necessarily want to have sex as much as I want to sometimes. Has this happened to anyone else? I also have been wanting to bang other people that I find attractive. Am I crazy or is it normal to want to have sex with people that aren’t ur spouse?
