Sex after giving birth

So my husband and I just had our baby boy two months ago. We started having sex after 6 weeks but since the first time we’ve only had sex a handful of times and I feel like I’m always initiating it, before our baby he couldn’t get his hands off of me. So anyway a couple nights ago I suggested we stick to only oral sex just until my birth control pills kick in and he quickly agreed. Since then he’s been initiating sex every night. I can’t help but feel like maybe something down there in my lady parts is different for him and so he’d prefer oral. Has anyone been in this situation or felt the same?
