I want sex he doesn't. help?

Bonnie • Been a single mom for 14 years then fate decided to put a wonderful fella in our lives. Life`s got quite the curveball.
He barely wants any and I would like at least more than once a week for 10 minutes. I don't know how to address this issue. I don't want him to feel obligated. I already don't feel very desirable. He works 7 to 3:30 and I work 4 to midnight so during the week it's impossible. Especially with a baby ok the room waking me multiple times. I still have to cross my fingers that he'll touch me on the weekend.
