You want her to give you a HJ, just not to completion?
(I would expect that most massage providers might ask you why in this case, if for no other reason than they want to know if it is something about THEM that is making you not want to finish)

Or, do you want her to just give you a massage with no HJ?

Are massage providers very picky about the clients?  I am an overweight guy with a big beard, probably would resemble biker in the right clothes.  Will that be a problem for most or are they used to different body types?  Also is it unusual to got to a sensual massage provider and ask that you not be brought to completion?

We're no different than "non-massage" providers, really.  Some of us are picky and choosy, others are less discriminating.  It's just a matter of personal preference, business style (some providers are more selective, and can be because they have a larger demand for their "product", while others cannot afford to be).  Or, their personal belief system sets certain standards in decision making along this line.

Personally, I do not care to pick and choose, according to body type (unless a prospective client is too large to lay on my massage table, or too heavy-for fear of it collapsing.  I choose to refer someone else if that is the case).  

In answer to your question about not being brought to completion...I can only say if it unusual for me, personally.  And, yes it is, but it would not be strange or offensive at all.  It doesn't matter if it is unusual.  The only thing that matters is that you communicate what you need and want, and that we deliver.  Period.  

Good luck, I hope you get a good rub!

and your weight will not force the table to colapse, no problem.  I agree with the previous lady is that "why wouldn't you want to experience a tingling climax?"  Sometimes a HJ can be very sensuous, even more so than FS or BBBJ (obviously depends on the provider).

I wouldn't want hj, but some rubbing or touching would be ok as part of the massage.  I am just looking for the intimacy of touch from a beautiful woman but not in a sexual way, if that helps at all.

That helps a LOT! We call that a Therapeutic massage! (non-sexual).
You just may have saved yourself some money.

"Sensual massage" implies but does not guarantee the availability of a HJ "Happy Ending". Since "completion"= orgasm, the original implication was that that you wanted to include a HJ, stopping short of orgasm.

If you are looking for more eye candy, such as lingerie, topless, or nude, you may need to see a "sensual massage" provider who lists that in her ad, or it shows up in her reviews. This part can vary widely and YMMV. Obviously, don't touch her without it being offered or without getting permission first. A "sensual massage" provider may also be willing to do more work on your glutes, inner thigh etc.

NOT getting a HJ should be easy. There is only a small chance she wouldn't get permission in some manner first (if this does happen just ask her to stop!). I did have a conversation with a massage provider where she told me she always asks what type of massage now, because apparently several years ago there was a client who got quite "surprised".

For what you are looking for, paying for a full session with someone like the lovely skilled and talented Alantra (above) would be like ordering a 5 course meal including wine and after dinner drinks when all you really wanted and were going to consume was a small house salad and water. (No offense to Alantra intended; I feel certain she's worth every penny and more, especially if you're getting the full "Alantra Experience").

You can search for a massage only provider reviews (sensual) on TER using the following settings.
escort available = No
massage available = Yes
incall available = Yes
agency/driver/independent = Independent

You can also use TER review search to search phone numbers of local sensual providers that have ads to see if they have a listing.

If you are looking for a beautiful (fully clothed) lady for a Therapeutic massage, that is easily accomplished in most locales. You can look at local ads and websites for therapeutic ladies that may suit your requirements.

When you contact a massage provider it sounds like you will want to mention your weight, in order to make sure that she can/is willing to accommodate you. It is indeed possible that her massage table may not accommodate someone quite large. I have seen a couple of providers that had older tables that felt pretty shaky when I got on/off, and I'm just slightly north of 200 lbs. I have also have been on sturdy tables that didn't even wobble with two persons on them If it seems like it would be more comfortable, you can look for a provider that offers massage on a futon instead.

Be aware of the style of massage that you're seeking. For example, there are versions of Shiatsu and Thai massage where you remain fully clothed. Draping requirements can vary considerably, sometimes depending on local laws.

As always, arrive freshly showered with fresh breath. (this may seem like a no-brainer, but it is a frequent enough problem that I know a provider that has a peppermint waiting on the table for each customer).

Relax and Enjoy!! A good massage can be a delightful experience indeed.
