But I do know what you mean.

I suppose it would be reasonable to suggest that she go and take a couple of minutes to shave.

(You first, then tell us what happened.)

Be careful what kind of material the blanket is if you don't pull it down off the bed.  An extended, enthusiastic DATY session once left me with bright red elbows, almost like a rug burn, when the lady was pushing down with her legs...tough to explain away...

If she's happy, I am a very happy camper! (diner?)

Yunno sporty, it goes both ways!!!

There is a provider here in the UK who refuses to see me until I shave!!!

She claims that I am the only bearded client she's seen, possible, beards aren't at all common here amongst punters, and as she says, it feels too scratchy and weired.  

Prior to our second visit, this was a topic of texts.  Unfortunately, I trimmed the day of the visit, and being summer, went for position 1, extra-close, maximum-itch!!!  I was trying to impress, but everything went wrong, but there was a happy ending, but no repeat visit!!!  I was last clean shaven 16 years ago!!!  

My best advise deal with it and say nothing (jmho)

OK, seriously, If you ask her to just go into the bathroom and give herself a touch-up you are going to wind up in the hallway outside of her room so fast you may not even have time get get dressed first!
I gotta say I was down on a muffin last night that had a few days of stubble  on it and it didn't bother me a lick!

As with any idiosyncratic aspect of a gal, see her once, if it's a problem for you don't see her again. Simple plan!

Lol, By the way, your lips are supposed to be on hers. If you are licking stubble you are doing it wrong...

a provider's delicate areas are not like a man's face.  A man can shave every morning and then again in the evening.  However, if a woman shaves too much she winds up getting razor burn and it makes daty and other activities uncomfortable.  Imagine getting a rug burn on your penis.  Also, to be honest, daty is not really entirely safe with razor burn since that means that there are scrapes in that area.

If the stubble bothers you, you can try rubbing a little lube around the outside area.  It will form a barrier and allow your skin to glide rather than scrape along the stubble.  It should help much the same as using hair conditioner on pubic hair makes it alot less abrasive.
