I have been with DH nearly 5 years, we have 1 ds and I'm also 7 months pregnant. For the first 3 years me and my dh had a great sex life.
In the last 18 months that has dwindled drastically to the point that if I didn't keep mentioning it, we have gone a couple of months without anything. The problem is I discovered a large amount of porn use during this time. So whilst I was trying to initiate sex he would turn me down but then masturbate to porn.
It all came to a head a couple of monhs ago, I told him it has affected my confidence and self esteem. I feel frumpy, unattractive and fed up. He has since not been on it ( as far as I know) but I'm still the only one most of the time that tries to keep our sex life active.
