SCENARIO - you need to take a leak. You're on the sofa, you need to go up the stairs and along the landing to the toilet. Fine.
QUESTION - at what point during that process do you get your todger out?
REASON FOR ASKING - I've started to notice (as has my wife) that I can be halfway up the stairs with my wang out, ready. I hadn't really thought about it, but it seems that it might be a bit weird. It's not weird, right?
