Spice things up?

Ashley
My husband & I will be married for two years this month & we have a three year old boy. Our sex life literally sucks. We both work full time jobs, but on top of my 40 hour work week, I'm doing housework & taking care of our child. By the time bedtime rolls around, I'm way too tired for sex, & I'm not in the mood. It's just not a "need" anymore to me & it frustrates my husband. We go weeks at a time without making love. Any suggestions?
