with my (now retired) favorite FBSM provider was me eating her. Another half-hour of her taking me to the edge until a final release, and the rest an actual massage.

whichever is less.

If not appropriate, at the very least appreciated. I am thinking the logic sort of goes like this: Someone comes in an gives me $400 and to earn it I lay on my back and have as many orgasms as I can in an hour, and I can even close my eyes so I don't even have to look.  Whoever asked 'is this a great country or what?' may just have done so after having such a transaction.

The longest I have ever done DATY is probably the same as you, about 45 minutes or about a third as long as the longest BJ I have ever received.

If you don't do DATY on ladies, then are some of them going to be reluctant to see you?  Many ladies obviously love it, but can it be a barrier to seeing some ladies (if you don't do it based on your reviews or profile)?

The women are providing a service for pay, and very good pay at that.  

Are you talking about with, or without, a snorkel?

Longest for me is probably 30-40 minutes but I will go as long as she seems to be loving it,
because I love to eat pussy.! And I think I  have gotten much better at it as I have aged. PATIENCE!!!!!!! Start Slow around the edges until she ready to be really licked. She will generally give you the signals,

Back in the day I met a lovely lady for the first time, and started the session with daty. She came hard, so I continued. The next time she came I noticed that a river started flowing. I'd never seen the likes, so I thought what the hell, let's keep going. After her third cum, I guess she started feeling a little guilty so she said it was my turn. I just looked up at her, smiled, and shook my head. I couldn't believe it. I was in the presence of a true nymphomaniac. She kept cumming, and I kept licking. Of course she was happy to go otc taking care of me. Now when I say the sheets were soaked, they were completely soaked, every inch. I was sad when she retired.

...I usually DATY her just long enough to get my juices running so that when she returns the favor it's over pretty quickly.  
With a civvie I guess I've been down there upwards of 30-45 minutes when necessary. Just an estimate since I've never  actually used a timer.

my longest is about 90 min, but that was OTC time, no clock.  On the clock, about 40 minutes during a two hour session, sometimes in one go around, and other times divided into two DATY sessions, depending on how long it takes her to cum.  I won't go more than 40-45 minutes when I'm paying.  If she's paying me, I will go until I have emptied her bank account.  I do tongue pushups to stay in shape.

I can't imagine it's been more than 15 minutes.

As an established provider, from experience it honestly just depends on the duration of the appointment.

15 minutes is about right for me with one of my fav girls who loves to be dined on. Learned this by reading all of her reviews which were very similar in this dept. This starts the session out on a real positive note and gets her in a relaxed  sweet mood for the remainder of the date.
I pretty much agree with and follow the same pattern as TennGambler cause it works. First time I was with her it was like she stuck two fingers in the wall outlet and got electrocuted when she popped. Quickly pushed me away from now being super sensitive. She then proceeded to give me a 10 minute tutorial about her "O". She explains that it takes her almost an hour to desensitize and cycle back to normal. Quality, not quantity is what its all about for her. Getting her off like this is a terrific ego boost for me and pumps my T-levels to the moon. Now calls me her "Cookie Monster" I luv it. Always loved Girl Scout Cookies, the over 18 ones.

If I count time spent in 69.  I've always loved DATY and will do it as long as the lady seems to enjoy it and my tongue still has feeling. Back in the day I remember a strip club where you could get this in the VIP room. Wish i could find again that dancer who squirted while I was going down on her.

... so I really don't know how long it lasts.  I only know I do it as long as she wants me to.  My last one was pretty long... and she was giggling and even laughing softly.  I asked her how she was doing, and she said "Just riding the waves" in a tone that told me she was in no hurry to stop.  So I continued until she let me know she needed a breather.  

My longest was 45 minutes. This client in particular wants to always see me happy more then anything else.

In a civvie relationship, until my neck and tongue cramp up.  I have done an hour or longer, then rested and done the same again several times in a day.  The stamina (of both if us) is the only limit.  Love to DATY and give multiple orgasms.
In p4p I still love to give it, but want my nut too, after all, I am paying.

In P4P, 1/3 of the time doing BBBJ is appropriate.  Outside of P4P, 1/3 of time doing DATY is appropriate.  

I love it to brother ....

I don't count time .. I will BBBj long as I enjoy it and him . I have for the most part men who love DATY & they stop don't  til they make me cum and I love to return the favor. I think it's personally preference. If the chemistry is right, vagina is yummy, she's into it ..,, there is no time limit. You want her to explode and verse vice...
