Sex drive affected by breastfeeding

I know this is the breastfeeding section, but I'm posting in here because I'm almost positive it's the breastfeeding that made me lose my sex drive. Before I got pregnant, I had a healthy drive, but now, I don't want to be touched in that way. Is there anything I can do to get my drive back while continuing breastfeeding? It's affecting my marriage because my husband doesn't feel desired. I kinda know how my husband feels, because when he was on anti-depressants, I was the one in his position! (Isn't life ironic?!)
