Let's see what we all prefer in terms of physical features of a provider. You may be super stoked about you ATF and she may not have these, but if you could craft the perfect provider for you, make your choice.

Breasts:
+ Nipples: eraser heads or big tips
+ areola: narrow ring or massive circle
+ Perkiness: Full attention or deflated balloons
+ Natural or enhanced

Overall body:
+ Clean skin or tattooed
+ Piercings or no piercings
+ Hard body or "average" or more cushion for the pushin'
+ 20-30 or 30-40 or 40-50 or 50+ (age)
+ Smoker or non-smoker
+ Blonde or brunette or black hair
+ Asian or caucasian or Afirican or other

Lower swimsuit region:
+ Bushy or trimmed or bald
+ pierced or no pierce
+ Kegel-enhanced or factory strengt

I'm a fan of any breast that is made available to me.  Love the perky, large massive circle  areola, enhanced or naturals.  Everything else is gravy and greatly appreciated!!

My preferences:

Breasts - Perky nipples and breasts are great.  Saggy--not so great.  Natural is nice, but enhanced is fine too if not rock hard... and I know some ladies who have highly skilled plastic surgeons, based on the quality of their work.  

Overall body:  No smoking, please.  Tats/no tats, piercings or not, hair color, race -- no real preferences there.  Age-wise, I prefer a more mature lady, i.e. 25-50, just because I'm olde... uh, more mature myself.  But age is not really an issue unless REALLY young.  I do appreciate a lady who makes the effort to care of herself physically.  Doesn't mean she needs to be fitness model material though... although if she were, I can't say I'd mind!  I love a firm butt.

Lower swimsuit region... I prefer shaved or at least trimmed, to bushy.  I would hope the reason would be obvious.      

One physical trait you left out is the hands.  Strong but soft hands are great, whenever massage enters into the picture.

Other favs, physically... soft, kissable lips; not too much makeup; eyes that grab onto my soul when I gaze into them; a talented tongue with lots of stamina; strong legs that don't know when to quit... OK, I have to stop this now, take a cold shower...

END OF MESSAGE

This is funny. That's a fact!

No doubt there will be one. I just hope it does not get mean or insulting. And, yes I believe there is a bit of double standard that favors us guys. We are allowed to crudely objectify the providers and they are not allowed to do the same, to the same extent.

"factory strength"?

I won't describe my ATF, but to me he is AWESOME, physically & other ways

If that's what I was relying on I would starve!

Some women have worked hard to use their muscles in their vagina during sex. (kegels)  
Factory strength refers to typical, non-exercised vaginal muscles.

I had a GF that could almost hold me in her because of her strong vaginal muscles.

The reason I do this is for the endless variety!

... when the lady is turned on (by whatever turns her on), she has more fun, and that's more fun for me.  

I do what I can too but I'm under no illusions as to what I bring to the table in that regard.
