Some of the answers to my post below asked if she knew that she was my ATF, so that got me thinking:

It's a feel good thing for sure  😊

you can measure the time you've known them in decades

Yeah, I'm sure a guy would never lie about that.  :-

show her she's your ATF. I had an ATF for 7 years. She got the drift because she understood my budget and availabilty.  

tell me that she was my ATF..

It may make the provider become more complacent though. So it's always a gamble.

too much for you and you want her to dial it back a little on the service.  Its human nature to get comfortable and not try as hard when they know that have a lock on you.  As another poster above says, they will get the picture based on the frequency or duration of visits.  If I am seeing someone for two or three two-hour sessions a week, they are quick to figure out that, while we may not be exclusive, I'm probably seeing them more than anyone else.

I've been told by a few that I'm their ATF and it makes me feel great
It makes it even better if I feel a genuine connection with the person as well.
AMAZING things can hapoen when two people like one another ;

And the providers knows it without us telling them

but I'm sure she knows, because she knows that she's the only one I keep coming back to see.  She knows I keep trying out other ladies, though, and she knows that I also like transsexuals...so she won't get complacent about it.

... you have been, and always shall be, my ATF.  (And my friend, too, but that wasn't the question.)

j/k but i bet if we met you'd be in the running!

and they both tell me i'm their atf's whenever i tell them.

it's like that old song (bonus points if you can name the broadway show it's from)  

How does fg show it

So yes each lady knows and all of them are very nice woman.

But I am a fickle bastard...

And the laugh...ya nevah know when I am going to be in a town near you dahlin....of course I have no idea where that is lol   kisses from the land of no R's 💋

agreed, an ATF should figure out they're an ATF by how they're treated. It's not rocket science and it's not 100% about the sex(maybe only 99% lol). This goes both ways. Generally we talk about a hobbyist's ATF, though there are plenty of providers who have their own ATF hobbyists.

Such a tacky title to label on someone....Almost wanna chase it down with brew and some jerky. If I liked my time with someone, I'll just tell them that "I had great time with you and I'd love to see you again"..nuff said....I would think, yes?
And usually the next visits are better then the first.

I BBFSCIP with her. So she knows she's my ATF.

Absolutely!!  No discussion needed bc actions speak louder than words.. I have my ATF client and my sense is they know who they are without asking.  Why talk about it?  Granted... I'm also the type who cherishes actions over words.  I tend to make sure he knows without saying a word.  😇

Since all of us here start our hobby relationships with several lies, I'm going to have a hard time believing certain things that are said. Things like, You're my favorite. I haven't cum like that in a long time. I love you. Your my first guy in a week. Your the only one I've seen today. On and on. Those are nice, and enhance the session, but really? The other thing you have to remember is that the hobby relationship, for the most part, is a perfect relationship. So our perspectives aren't exactly coming from reality. Lastly, as one of my atfs used to say when I would say something from cloud nine, "Oh, that's just the sex talking. You really don't mean that."  

Hmm... Not sure what I think about that one... Rule of thumb is that the type of behavior you described is best kept to monogamous relationships.. Just food for thought. Safety first!!
