I've always thought that asking whats on the menu over the phone was bad form.  But if the only review  makes no mention of what I want, is it alright to ask?

I've had this come up for me as well. My opinion is that no, it's not alright to ask. Perhaps it would be ok once you've been screened by the lady but I've always played that by ear so to speak, depending on how my communication with her has gone up to that point. I'll be interested to read what others have to say.

and it's OK.  Most providers love us to pleasure them, I think they consider it a bonus.  I have never been refused, in fact, most are very happy to let us dine at the Y.  The gals I have seen have always been very receptive to me going down on them.  I enjoy it very much, btw.

You may be able to get away with it if you are slick enough to pull it off, but most women will not give you a laundry list.

If DATY if your thing, then your best bet is to couch it as, "You know, one of the things I enjoy most is pleasuring a woman.  I hope you are into that as much as I am."

But it's a sticky situation, and you have to be able to read it well.

Most cannot.

wait till she gets more reviews, or see someone who offers DATY.

DATY is very common and you will find plenty of girls offering it. No need to engage in any kind of communication over the phone or otherwise.

My earlier post was assuming the OP wanted to ask before meeting with the lady. I stand by my comments but should have gone further and said what swim has said in this post. My bad. I agree that it's fine to ask once your alone with the lady.

Find a lady with more than one review, and reviews that tell you she offers what you want.
