I have never seen a provider and I'm nervous. I dont know what to expect and how to act when I meet for my appointment. I have 2 that I'm extremely interested in. Both of them are probably the best shape and well I'm a dad bod. Are providers picky about that? I have so many questions because like I said before I'm all new to this.

do not care what shape you are in.  They want you to be clean, drug/disease free,  a gentleman, and not a time-waster.  Don't show up drunk or high.  Don't try to negotiate their fee, see the ones that are within your budget.  When you see a lady, it's nice to bring a gift.  I always give them a candle, (you can get them at Walmart for not much $).

I mostly agree with swim, except as noted

do not care what shape you are in.  - I agree.
- They want you to be clean, drug/disease free,  a gentleman, and not a time-waster.  - I agree with all.
- Don't show up drunk or high.  - Agree.
- Don't try to negotiate their fee, see the ones that are within your budget.  - Agree, agree.
- When you see a lady, it's nice to bring a gift.  I always give them a candle, (you can get them at Walmart for not much $). - I don't completely agree. Check her website or even reviews. Some indies specifically say that they love gifts and provide a list (oftentimes expensive lingerie or specific wines). It also depends on touring versus local; incall or outcall; hotel or her place: a candle for a touring provider in a hotel will end up in the garbage or be left behind. And so on.
.  
- Check their reviews, give them your info that they ask for.  If you are not comfortable with what they ask from you, move on, there are plenty of others out there. - Agree. The what they ask for part is usually a lot of personal information. Read more posts to Newbie and General and think about that carefully. If she insists on some info you would rather not divulge, think with the big head, not the little head, thank her for her attention and move on.
.
- Good luck, - Agree.

But I have to add that your timing seems pretty UNlucky. There are major coronavirus restrictions on travel, hotels (many are officially CLOSED), sit-down dining, doing ANYTHING non-essential that brings you into contact with crowds. And you might be exposing yourself or your hostess to getting COVID-19.

Stay tuned to various TER boards to find out what other, more experienced folks are doing and recommending in different cities.

Many gals have a suggested gift (as opposed to rates) section on their sites and often some kind of beverage like wine or in the case of one gal I recall, a single malt scotch is mentioned.   However, if this gal you are seeing is in traveling mode and presumable catching one plane after another, then having a bottle of liquid is not particularly user friendly for them.

I dont plan on going out in public with them just doing an incall at their location of choice. I'm assuming it will be basically talking for a few and then the services will be met? The 2 I have chosen have wish lists on amazon that I plan on purchasing and mailed to them.

...something that may be difficult to get in their bags.  Like mrfisher says, something small.

Lol yes maam

What do you expect him to do, ask the providers to "indoctrinate" him?

Your response when considered with swims advice means you want the newbiw to be dirty, stinky and diseased when he comes to see you.  

I guess we can’t say the same for stupid answers. Maddy’s post may be the stupidest answer ever, on the newbie board. If she can’t give constructive useful answers on this board, perhaps she shouldn’t post here.  

I've only been doing this actively for three years although I signed up here six years ago.  At first it is hard not to treat it like dating where you worry about being acceptable to the escort.  We want to seem charming, intelligent, handsome (at least not ugly.)  
.
I am sure they would appreciate all that too, but it isn't the dating world and they will likely forget you the minute you walk out the door.  Of course every provider wants to have an enjoyable time, but first and foremost they want to get paid.  Money is the great leveler in this franchise.  Just out of respect for human dignity, I show up showered, shaved and sober -- as I would for meeting anyone.  I am polite, strive to be on time and leave on time.  I am not handsome and have no game.  But I've always been invited back.
.
If every guy was handsome and charming and had women falling all over them, escorts would have no business.  So just think that you are providing her a life saving income.  She should be thankful you showed up.

I don't bother with a gift the first time I see a girl. Even with girls I see multiple times/regularly, I generally just put more $ in the envelope.

I actually took it in the humorous "war of the sexes" vein.   Warning against taking Maddy's advice is similar to warnings on lawnmowers not to stick your hands in the revolving blades.  Everybody realizes that.
.
I actually have more fun with ladies who are playful and frisky like that.  

My 2 cents, repeating and in addition to what others have already said. Think of it as a first date with benefits. Read the ladies reviews like you are preparing for the date. Be civil and no politics until you like and know the provider better and vice versa after multiple visits. The great thing about hobbying as long as you have the budget is there is no baggage. Again, like dating, you have to see many ladies and expect the good and bad. And YES, make sure you are squeaky clean, especially the boys and your breath smells minty fresh.  

I’m in very good shape (just what I enjoy) and have had several ladies remark that I’m an outlier. As with everything in life, these gals are probably used to seeing a mix of clients. But as others said, be clean, be respectful and follow the girl’s instructions. Have fun!
