More Sex?

So my fiancé & I have a delimma...he wants MORE sex! I don't have an issue with it but I'm so consumed with work, chasing behind our toddler, keeping up with my social life (birthdays, meetings), planning our wedding, keeping the house cleaning, cooking the meals, sexing him & still try to make time for myself to keep me sane (a long bath, a pedicure)! & sometimes I'm just too tired or not in the mood because of my lifestyle. What can I do to get it in more often? Is there a balance? #HELP
