postpartum feeling toward sex

i am about 4 months postpartum and i have barely any interest in sex, at times during foreplay i get a weird feeling like i don't want him to touch me, almost like a weird feeling like if someone had come up to you that you didn't know and basically is trying to molest you. i love him more than anything and still have strong feelings for him.  and i miss my sex life, but has anyone else felt almost like a "don't touch me, it doesn't feel right to me" feeling?
