I recently saw a provder. Young, cute, petite amazing body. When I removed her underwear there was an aroma I just couldn't get past. It killed daty for me and almost made me rethink the act. I felt bad. I didn't want to say anything to her. But is there a discrete way to mention this to a provider? Any suggestions?

Keep your mouth shut, both literally and figuratively.  Or just grin and bear it (like a shit-eating-grin).
Honestly, I don't believe there is a way to tell any lady, that she has a stinky hoo hoo, without her being offended.

You didn't have the balls to say anything, or even make her take a shower? Why would you feel bad if her snatch smelled like garbage or her trick's jizz from the night before? Shouldn't she be the one feeling bad?

Hmmm....maybe because I took into account she is a human being and has feelings....apparently that's a novel idea to you!

I get that she is a human being and has feelings, but that doesn't excuse her from having some basic hygiene.  How many times do you see it on a gals website or p411 profile instructing us to arrive freshly showered, etc.  You have every right to mention it and should... It's the only way she is going to clean up her act (pun intended).  You don't have to be mean about it, but politely let her know that you find it offensive. SMH.

with yesterdays cum from her prior johns.

If you knew me Pansy would be the last thing you would call me.  I have been called many things: Gentleman, Good Neighbor and Soldier, at times Asshole, SOB,  Prick and Vato Loco, but,  Pansy?.... NEVER!

Who is the Pansy?

Ben there and sadly the girl I saw was pretty hot. Never saw her again!

Vaginal odor is typically from inflammation of the vaginal area. Inflammation of the vaginal area can occur because of poor hygiene but is often a result of infection in or around the vagina. A common infection that can cause vaginal odor is overgrowth of the normal vaginal bacteria to cause bacterial vaginosis. The sexually transmitted disease trichinosis can cause vaginal odor. Uncommon causes of vaginal odor include cancers and an abnormal passageway between the rectum and vagina (rectovaginal fistula).

Pre-menstrual secretions and post menstrual residue compounded with post menstrual secretions add to this ovulatory mucus.
From my  experience (having been previously married for 12 years and having cohabited with 3 ladies) post menstrual  residue, is a very common, source of vaginal odor.   Of course this is only anecdotal.  

Follow the thread, Airhead. (Another to add to your list)

Perhaps, if I had a lower IQ, I might just appreciate some of what you post.......NAW!!
Go back to the general board, where you belong  Along with the other losers.    
Boy, you must have had a terrible childhood..  Poor, little guy!  Mamma's Little Man...  

Are you done researching about vaginal secretions and did you use your panties as evidence to come to your absolute conclusion that said hooker isn't dirty but is a victim of circumstance?  

and potentially lots of fun. I think the 1-hr or "short stay" guys worry about "losing time"; I'd probably think twice about ruining the organic flow of the date... we're right there in the moment and: pause. shower. If the situation demands it however - I'm with you; hit the shower!!

Here's a helpful hint on how to tell her in a healthy and ho-listic way...
