First of all, GREAT THREAD!
with me, it kinda varies.
Sometimes I just want to stay all cudlly and we just crawl real thight towards each other holding each other for a while. Then i don't start "cleaning up" right away. I like to stay a bit messy for a while and just be held.
Sometimes it even happens that we fall asleep and I wake up in the middle of the night all ... jekkie... you know. Then, depends on how tired I am, i either go to the toilet and 'pee it all out', or I just take a tissue (we always have some near the bed-area) and wipe it up a bit.
Other times, i just have to clean it all up right away and I can't really stand the ikkie-feeling at all. In those cases I wouldn't be able to relax until I'm all nice and clean down-under again.
