sex after baby

so i had my baby 2 months ago, me & my husband had sex for the first time after i had him & saturday it was soo good , then we had sex again sunday, but this time once i “finished” , we still kept going bc he didn’t yet but i couldn’t stay “wet” he didn’t say anything about it but ive been thinking like why did that happen? could it just be from having my baby & my hormones? or the condom? this is our second baby i dont remember this happening after our first but also never used a condom either?
