Not into "IT" anymore

OK not what to do..... before baby boy came along my sex drive was great.... got pregnant and I couldn't stand my husband touching me at all. Only had sex so this boy would come out. Now my 6 weeks came and got the clear and I still have no sex drive. Really sick for my husband and even had little smart ass coments of "my hand and imagination can only do so much"...... what to do seriously. I don't want to just do it to please him.... it use to be fun
