I need advise, or someone to talk to.

So I need help. I'm bisexual. I've known forever, and I've been with girls and guys. I'm married to an amazing man that I love very much, but lately I haven't been very sexually attracted to him. I think it's because I've been missing having sex with girls so much. It's been 4 years since I've been with a girl. I wait until he goes to bed and watch lesbian porn and masterbait, because I dont want him to think it's his fault at all. He's totally cool with me having sex with women, I'm just really not comfortable enough with my body since I had my baby to even try and sleep with a women i dont know what to doooooooo😭
