I'm scared there something wrong with me 😢

So before I got pregnant with my first baby every time my bf would touch or robbed my nipples I oils get so much turn on and horny and ever since I had my baby now when my bf sucks on it or plays with my nipples like I don't get horny I think it's sexy but like I get no feeling like I used too . Before I would get this feelings on my boobs that felt so good but know when he plays with my nipples or sucks on them I don't feel any good like I don't feel anything 😢 could bthere be something wrong ? My bf didn't know anything about this I just tell him it does feel good when it dosnt and no I didn't breast feed my baby at all since I had a miscarriage. I used to get honey just by him touching my boobs but know that dosnt get me honey unless he's touching me down there amor kissing my neck
