No sex drive after having a baby?

Anyone else experienced this after having a baby? I used to be very sexually active, i used to be always the one over my partner to want sex , constantly, every day. I used to watch porn and mastrubate. Since having a baby 5mths ago i cant get horny by myself ! Of course when me and my partner get to doing the thing he turns me on but i cant at all get myself going, the thought of watching porn and masturbating makes me feel sick now. Is this normal?? I miss my horny days 😂😂
