Will usually shower at the WGs place, sometimes because it's after work and I'm sweaty or grubby, sometimes because it's a confidence thing for the girl (one less excuse) but also sometimes because then my kit (clothes, car key, punt phone) are in the bathroom. There's been a few tales of woe with guys getting trapped in the bathroom by Sergei or the girl, and of wallets/clothes being grabbed if it goes south. It's harder to pull that sort shit when my kit's in the bathroom I reckon.. opinions differ, of course. I'm sure there are scenarios where kit in bathroom is a disadvantage, other than getting your shirt wet.
