I’m 31 years old, from Argentina, but currently living in NYC. I’ve only had sex twice in my life, so I have very little sexual experience. I’ve always had the fantasy of being with a pornstar.

You might want to check on the Porn Star board as well as there will be more there that share your fantasy and have some suggestions to make. Some here will also have some but from prior threads on this the impression I have is that it's just not worth it really -- unless there is a specific star you want to have sex with. Seems that most of the porn stars are going to ask much more than the average provider, and will think they don't really need to give the same level of performance as your average non-porn star escort.

There are a lot of guys with plenty of experience who frequent that page. Personally, I've been with a few but am not an expert in that area.

I’m a professional woman of leisure and I would recommend a mature, experienced & a person with patience. What are you attempting to accomplish? I don’t think your porn star fantasy will be what you expect.

OP needs to learn to walk before he learns to run! Booking a porn star is usually not for beginners. You should want to bring your A-game for one of those girls. Plus you need to be good at sifting through reviews and information to make sure you get your money's worth. As Jensen said above, there are many porn stars that rely on their fame while phoning it in during the session. You have to find the ones that actually seem to enjoy what they do. Start slow with some well reviewed providers in your area and go from there. Then, when you're ready for the big game look into booking your favorite stars.

Doesn't Titus sound an awful like a gentleman we just experienced???  

BDSM, threesomes and pornstars are 3 of those off the top of my head, from my experience. I have seen 4 women that do/have done porn, but only two of those would be considered "stars." I have to admit I was very nervous the first time, but had a blast. I saw two bucket list girls (one of them I saw twice) and it was thrilling.

Do what you want, but since your sexual history is very brief, maybe wait a bit on the porn star thing. Good luck either way!

So you will get the best fakery money can buy, but with your limited experience, you may not know the difference.   For an upcharge, some will even let you record the encounter, but you have to bring your own tripod set-up.  You'll walk away feeling like a porn star with a video you'll be proud to show your mom and her friends.

Can I send you a DM?

Like others have said you may want to warm yourself up with a quality escort at what is generally a better price point than a porn star. Read reviews and try to seem those who offer a more PSE type of experience if thats what you looking for I saw a few girls in a row who made me feel as if I was in a porn movie could not have been better and though I have been with a few porn stars who really delivered I stay away mainly because the one I do find reviews of average 7s and 8s for service which is just not gonna happen with me at their prices!

I seen a girl who did porn. Not a big name. Her bbbj was terrible . She would do the porn face while doing it. So it stops the rhythm and is freaking annoying 😂  She was good in other ways though.

I've read a bunch of reviews and posts, but I would ask you, "What are your expectations?" If you are expecting to "get" what you see in the videos, don't count on it. Bareback? Anal? MSOG? Rough stuff? ... ? Some porn starlets reserve that behavior for pro guys who have a history and recent clean STD records; guys who know how to make it APPEAR a certain way but to not cause actual pain or other problems. Some of those 10 minute porn scenes are the edited-down versions of 60 minutes of action with various breaks ("Fluffer!") and interruptions ("More lube!" "Wipes!! He shot in my eye!") and so on.  
.
Paraphrasing older reviews: "She does anal, rough throat fuck, ..., ..., CIM, swallow ... in her scenes but with me, it was NO DFK, NO BBBJ, NO Anal, NO CIM, ..." and so on. A big disappointment.  
.
Many porn stars have price points based on their celebrity status, NOT on their performance in the room.

From your post, it seems like you are looking for patient, helpful "newbie" experiences. There are Providers who can provide that. If you think that's what you are looking for, consider making a new post to NY Board (since that's where you are) about "Seeking Newbie Friendly Provider."

Sometimes porn stars are just regular actresses playing the part of a sex-crazed nymphomaniac. Behind closed doors (BCD), you want to avoid a circus!

Good luck! Have fun!

No kidding. First thing I thought when I read this.
The next character to be created will be a sex addict that is looking for more suggestions.

Rocket science.   Whatever your motivate is and whoever you said you are . Good luck to you,

Yes I think it is Ricardo. Too many similarities. Age, experience, vernacular and putting the cart before the horse!  

My first thought, exactly.

... who posted incessantly trying to hire provider to lose his virginity.  

Titus,  

Can you give some names or recommend me anyone for my case?

Again, I'm not current.  Reviews are your friend on that one!
