Are there any pornstars based in Las Vegas, or ones that visit Las Vegas?  
TIA

They have a fair amount.  I hear Paisley Porter is fun.

You may also check Eros, though Vegas listings are Porn outliers.  Way more than any other city.  Many ticking the box that probably shouldn't.  Look for familiar names.

I did a search of TER Reviews with only two criteria: Location: LV and Service Information: Porn Star
.
Plenty of recent hits but I don't recognize any big names. And keep in mind that TER "PS" could mean "any amateur who posts a few low budget selfie-videos to pornhub."

Oh. But that's not a name I recognized. I only watch porn when I accidentally click on a pornhub link.  
.
The 42 most recent (LV + PS) reviews (almost 3 pages) are all less than one year old.

That's what I tell my wife when she catches me.

I was a subscriber of yours, good content !  I didn't know you were in Vegas. I'll have to get in touch

According to her, you have to be good looking:

Do you have reviews or a website that lists your donations?
