No Intimacy After Baby

My husband and I welcomed a baby girl 10 months ago. I am still breastfeeding and co-sleeping. I'm afraid that our sex life is non-existent because of it. I don't know what to do. We have had sex 4 times since our baby was born. Prior to pregnancy and all throughout the pregnancy we had a very healthy sex life. However, he did complain about always being the initiator. He no longer sleeps in the bed and opts to sleep on the couch every night. I feel like we're roommates. I want to move the baby out of the bed and into her crib, but part of me feels like she benefits from the bonding of co-sleeping and that I'll feel guilty if I do. I have to take steps to fix this asap. Has anyone else dealt with something similar? Are there any moms who have suggestions on where to start with this?
