I've been with a few ladies who have actually denied me that.  That was something they just didn't feel comfortable allowing me, at least, to do.  Some of the reviews I've read of some of these same ladies indicate that was allowed with other guys but when I was there it wasn't allowed. On the flip side, I reviewed a lady I had seen and someone else reviewed her and indicated she didn't allow him DATY even though with me it was allowed, almost to excess, and that was my first time seeing her.

In another instance, the lady indicated she didn't allow that the first time she saw someone but it might be permitted on the subsquent visit. When I saw her the second time, she allowed it but was reluctant to do so.  Other ladies just laid there as I stimulated the hell out of her pee-hole (I presume) and didn't flinch one bit.

In yet another instance, there was a provider I had seen who allowed me to DATY the first time I saw her and she even gave me instructions on specifics and thanked me afterward.    I saw her again after 6 - 12 months had passed and she didn't allow me to do it at all.    Go figure.

What I like is when I sometimes surprise the lady I'm with as I get a kick out of her reactions.  

I actually love it when I'm given direction or if the lady is comfortable enough with me to communicate what she likes to me.  Sometimes I'll ask how she likes to be touched and she'll say I'm doing everything she likes already.  I'm not sure if she's serious or just not open to telling me how to touch her but I roll with it and keep doing whatever it is I'm doing.  

By the way, thanks for the tips about you... I'll keep them in mind.

When it comes to the boundaries, I'm not one to assume she's open to anything so I've come up with a way that I address the boundary issue.  When we're getting started with foreplay and I'm ready to "dive in" and start my full-body-worship (FBW) technique, I briefly stop what I'm doing and will inform her that I tend to be an oral person and that she should advise me as to which areas are off-limits and I'll be sure to steer clear of them. (I don't use that exact wording, mind you.  ).  I also tell her that I'm open to doing just about anything SHE is open to having me do so she should not hold back if there's something she would like for me to do.  In one case, the lady wanted me to worship her feet and was reluctant to ask me to do that for her.  When she finally got that request out, I told her that not only was I ok with that but I was *the* person to ask to do that.  I then proceeded to damn near swallow her feet and she loved every minute of it.  

I've found if I can do what I can to make sure the lady I'm with is as comfortable as possible, things tend to go a LOT more smoothly.  Sometimes I'll get wrapped up in the heat of things and will do things or try things (gently and carefully, of course) without asking permission first and other times I'll ask permission first.  It really depends on the lady I'm with.

Tongue fatigued is something I'm constantly working on and I'm trying to figure out ways to take breaks without disrupting the mood.  Practice makes perfect and I can use ALL of the practice I can get!  

Now about savoring the nectar of your passion fruit... if you haven't had "enough" of DATY I think any session we have together would end up being a very long one!    I've got TONS of fantasies revolving around this (I think I've mentioned that before) and am always looking for opportunities for doing it whenever possible.  I sometimes fantasize about seeing a woman in the lounge of a hotel where I'm staying and I walk up to her from behind and whisper in her ear, "I want to pleasure you with my tongue" and I slip her a piece of paper with my room number on it and go to my room.  A little later there's a knock at the door and it's her (it's MY fantasy so she shows up, damnit!   ).   I drop to my knees, lift up her skirt and start working my magic... right there in the doorway.  

Let me stop now.....

Peace...

Hi Carlee, thanks for your thread. Like MA, I have had some instances of providers who declined DATYs. I guess those were the boundaries of the intimacy they were ready to offer in sessions, and I understand.
On the "endurance" question, I found the very interesting article attached (cf. the "Rest" section, using the jaw, head or even whole body for tongue movement). I'd be interested in your feedback on the overall relevance of this article.
Thanks!!
--Love
