Low sex drive

Jasmine • Mumma to my beautiful girl born 13/2/18 👶
I've been with my man for just about two years. 
And I never want sex anymore, and when I do I don't feel good like I usually do. 
I love my man and he makes me happy. But why don't I ever want sex? 
It hurts his self esteem and I feel super bad 😔
