Ever since ive gotten pregnant with my son last year my sex drive has been really low. I got put on birth control after I had my son and I just never want to have sex with my SO anymore. I feel awful about it bc I really love him and I am attracted to him but I never want to do anything. And when we do have sex if its even once a week, I dont enjoy it or get in the mood as much as I did. And its actually painful sometimes I get cramps an sharp pains.. whats wrong with me?
