So I have seen this girl three times in the last couple of months and want to continue at least once a month. One of the main reasons for an LTR is to get a reduced rate right? But how do you ask about this without breaking the cardinal rule of not talking about money? Any input would be helpful, especially from other providers out there.

Being a once-a-month regular is not going to get you a reduced rate from most ladies. More frequency may help but many gals don't offer a deal no matter what.

The concept of not mentioning money only applies to the initial meeting.  Once you have established the fact that you or she are not LE it's OK, though considered tacky by some, to discuss finances.

I would be a bit careful about approaching a provider with the assumption that you are ever OWED a discount for your business.

Some ladies will offer a discount .... SOME. But it is up to them to bring it up and make the offer. If you ask or hint at it you will be shown the door and likely will never see her again.

I have regulars that visit weekly for years and don't get discounts. Our rates are as listed. If you want to play you pay the price of admission. This isn't the civvie dating arena, it's a business transaction no matter how much you like one another.

Main reason for LTR is actual relationship.

extend some additional benefits to you as a "regular" client, then that is her call.  This usually comes in two forms.  One, you might be grandfathered into the rate you paid when you first met and not have to pay more as she increases her rates later on.  Secondly, she might allow you to stay a little or a lot past your time.

seeing a provider on a regular basis, does not imply you are going to get a reduced rate.  You have seen her 3 times in 2 months, and think that deserves a reduced rate for future visits?  Wake up pal, because you are dreamin!!!!!  If you ask this girl about this, she will probably laugh in your face, and/or show you the door.

If you want to keep seeing her, by all means, do so, but most girls will tell you in no uncertain terms that their rates are NON-negotiable.  It is considered extremely poor taste to even ask for a discount, just because you want to see her a lot.  The rate is the rate, take it or leave it.  If, after many more than 3 visits, she offers you a better rate, fine, but don't expect it for quite a while.

You might get (as I have) been grandfathered if rates go up over time.   You will not need to be screened each time...  less work for her & faster appointments for you.  You might even get some prority booking.
However, the appointments you have booked is just scratching the surface.  I have Favorities I have seen over 5 years and I would not expect a discount.  I know others have had favorites even longer than I have.  I do get priority bookings, extra time...  even a lot of extra time...  
Asking about discounts is risky...  you may turn her off and get NO appointments.  Even worse, she might feel pressured & give you a lower rate but then give you lesser services.

That is what I need to make per visit to make ends meet.  

How often you hobby with me does not change the amount of my mortgage payment due, electric bill due, yadda yadda yadda.  

Negotiating leaves a bad taste in everybody's mouth.  Don't do it.

Do you realize how many guys contact us with this very same promise and if we go along with it do you know how many of them actually follow through with it?  

This "give me a discount and I'll see X number of times per week/month" is also known as the one of the oldest tricks in the book by providers.    

I'm sorry but a bazillion other guys have already thought of trying this and a bazillion ladies have been burned by it and now we know better.  

I have actually seen it at least implied on a few providers sites. But thats why I am asking the community, thanks for your info.

Thanks for the reply, I didnt think about that part. I was just thinking about it as a business and in my business which sells products and services i know that some service calls that i charge the same for are a lot different. some i would not do again for twice the price and some i would do for half. If i had that easy job as a regular thing i can count on i would do it for less, it's about volume. Nothing personal just business, although with the feedback I have seen i think it best to not bring it up.

Regulars may very well get an occasional discount or other benefits, but as you have said even in your business it is up to the supplier to decide who is a good regular they wish to offer this to not the customer. First you have to become a good regular at her price, and then she may decide she enjoys your sessions enough to offer specials to keep you a regular. Asking for a discount up front is like the customer with a chain of business trying to leverage his clout. 9 times out of 10 the extra business is not worth the aggravation and he is not a loyal regular, as soon as a better deal comes along he is gone.
First prove your a loyal regular customer and then if you really are you might get the specials that show she appreciates your return visits. As other have said it might not always show up as monetary but in little touches such as getting up extra early to squeeze you in before she leaves on a trip so you don't have to wait for her return.
