Husband with low sex drive

Claire • Married 12•29•12. Living and loving our lives with 2 precious fur babies. Talking about starting a family very soon!!
My husband and I have been married for almost two years now. I was a virgin when we started dating 6 years ago and in the beginning our sex drive was amazing. Being he is my only sex partner, I feel like I can never get enough!!
 Unfortunately, he has had 2 emergency back surgeries since then, and therefore has no desire to have sex. He lost a lot of feeling and his medications have really lowered his libido significantly. We have talked about getting pregnant very soon, but every time I initiate sex, he's not in the mood.
​How do I try to have a normal sex life again without making him feel bad, and satisfying my own needs at the same time?
