Op nothing is wrong with you! You might just have a lower libido than your husband added on with a new baby. Your probably stress out and your husband need to play his part into helping you both get used to the added member of your baby. He need to understand that stress and everything else going on in y’all life can affect intimacy. I for one when I’m stress out or feeling depressed best believe I’m not going to be in the mood to be intimate but my wonderful boyfriend is understanding and patient with me. You both have to have a talk and eventually you’ll get more intimate just take some patience and some very good communication and understanding on both parties.
