Relationship Intimacy

Good morning,

This is an uncomfortable question to ask, but I'm curious as to how often other pregnant women are having sex. My fiance and I had an energetic sex life before pregnancy & now its nonexistent. I'm 37 weeks and have 2 other children by another man who I had a very healthy sex life throughout both pregnancies so to not be acknowledged at all physically during this pregnancy has done a significant # on my self-esteem. Is anyone else experiencing this? How are you handling it?
