How to properly do aftercare after sex?

Hii! This is coming from a (19F). My bf does cum in me and I don’t really know what I’m supposed to do afterwards. I do pee after we’re done and kinda…push it out of me, even before he came in me I would still pee afterwards. And he actually does the same. But I’ve noticed that sometimes when he does cum in me, I do get a bit of an odor sometimes. I guess sometimes I don’t get all of it out, idk or maybe his sperm just throws my ph balance off or something. Should I be douching? Should I shower immediately afterwards? Usually what I do is immediately go pee and wipe myself with baby wipes, and depending on the time of day, sometimes I’ll just instantly shower.
