Orgasm not the same!

Anyone else’s orgasms not the same after giving birth? I found out I was pregnant July 10 2017 and have not had sex since then because my SO was afraid to hurt the baby so like a normal woman I turned to my vibrator whenever I needed an orgasm. Well while I was pregnant the orgasms were great and quite intense! I am 1 month PP and while my SO still won’t have sex with me I turned to my vibrator and needless to say I was completely disappointed. It felt nothing like it did when I was pregnant 😞😞😢
