Low sex drive..

How have you guys dealt with low sex drive? I use to have such a high high sex drive before I had my son and it went perfectly with my husbands. But after we had our first baby my sex drive us in the gutter, I love him so much and the sex is beyond amazing. But I just don’t have the urge anymore, and I feel so bad because my husband wants to have sex so badly, I’m always rejecting him or falling asleep early so we don’t have to have sex. He understands that my sex drive took a dip and is so sweet about it. But I wanna please him too, he acts like a caged animal sometimes.
