I think you may have to ask providers if they will take a shower with you.Otherwise it means they have one for u to use .I know many Asian consider it standard procedure, read the reviews that's what there for.

... I've never done it at the start of a session, as I always come freshly showered.  Also many providers like to have their hair just-so at the start of a date, and a shower could ruin that.  But if the provider were willing, I agree it would be a great way to start.  

I have taken a shower with a provider at the END of a session several times, and a couple of times in the middle of a session, and those were all a lot of fun.  One thing I haven't done with a provider yet is a tub bath... something for my must-do list.

One time I knew I was going to not have a chance o get a shower so the now retired provider asked if I would mind he waiting her taking hers and we could do it together.
Was a great way to start out except the shower was not real large and there was not quite enough room for me and her boobs. Come to think of it did not complain and would do again in a heartbeat .
I really miss that lady.

And it might be better to wait until you've seen her then, assuming you are interested in seeing her again, bring it up at the end of the session for the next time.

P.S.  I've done the tub thing a few times when we are in a room with a jacuzzi tub; it's a lot of fun!

My, at the time favorite in this world, and I started in the shower.   Also finished in the shower.  Hence the new acronym was born.  Hour in the shower.
