You guys are all fucked.
I push the condom off from the top, and pull the tip out as I do... my dick isn't a scaly piece of shit so it slides relatively well.
I give the girl a towel which I would have had conveniently located. Or, if she under 23, I hand her a t-shirt.
If it's nighttime, I then fall asleep with my dick nestled in her rear.
If morning, I ask if she wants to shower.
Not complex, just makes sense.
