Well you get to choose the girl so the experience relies on your judgement. "Some girls do and some girls dont" (have fun in the room). If its possible in a few seconds I try and pick one who appears happy at the prospect of an hour with an old fart, or a least one good at acting, which comes in handy later!.
Once in the room you can fine tune your choice with a few questions like " are you OK with DFK". At this point you can still back out.
The few times I have been there one was very ordinary and 2 were great. One lass could squeeze your dick inside her and thought it was fun to do so, so did I. There dosn't seem to be any house standard formula so you can make it up as you go with a willing girl. Showers in the rooms I used. Clean beds and linen.
