I'm sure many of us hobbyists walked out of an appointment with a big goofy grin on our faces.  That grin: .  I'm also sure we had to take effort to downplay it, as not to look weird to people and/or get figured out.  But with a mask on, no one can really see the grin; the mask is covering the biggest grin giveaway: the mouth.  Well, people say we smile with our eyes too---in fact, they're the distinction between a fake smile and a sincere smile---but it's far less obvious.

A little bit of Mystery  is Exciting too

After a session last week with 2 hot dolls, I washed up as usual, put on my mask and headed out. A moment later I realized that smell inside my mask was from all the DATY I'd just done. Yeah, I probably need to wash up a little better in the future. But I LOVE that smell!

back in the mid 80's to the the mid 2010's I wonder if it would have had an unintended benefit of me getting p for freeee.  
Everybody is hiding their ugly faces now. If when I was a kid and younger me, if I had hidden my ugly face. Would I had gotten into the hobby full time or would I had dated like normal people do?  
I don't know let's ask the people who still count. As for me I do wear a mask when I go inside some place that requires it.  
I'm not like those that start a fight or even kill others when they start getting mad for being told to wear one.  

The mask only masks VISUAL assessments. You would need to wear a ball gag or sever your vocal chords to control your VERBAL emanations to mask their AURAL assessments. Or convince everyone in your nieghborhood to wear noise reducing ear plugs.  
.
You might also have been done in by NASAL perceptions or your AROMA but TER doesn't have Smell-o-Vision for us to figure that out.  
.
We would probably not be getting to TASTE and TOUCH so I won't bother with those.

to remove the stain on my mask after DATY?

Iron Out is good at removing rust and the red stains from hemoglobin (iron) in blood.  

Since I saw a girl who's pussy juice would stain something.  You just need to move upmarket a little and the problem will fix itself.  

from the high two figures to the low three figures...no discernible difference except my wallet is a little lighter.

I wasn't much of a looker in my early 20's, either.  That's what drove me into the hobby in the first place.  With the mask covering more than 50% of my face, who knows how my civvie approaches could have panned out.
