Need some advice. I'm pretty sure there's a couple of working girls in my apartment building. I'm fairly positive i've seen mongers come and go. I'd love to confirm and make an appointment. However, I've never met them and I don't have their "work" number. I also realize the potential hazards. They may not want clientele in the same building. If they get busted by the super they might take me down with them. etc.

I do not think you should ever go fishing from the neighborhood pier. I am sure there are plenty less crowded and anonymous fishing that you can enjoy in your area without the worry of it disrupting your home.

"You don't defecate where you consume sustenance." I don't know if thats the exact saying but I think it's pretty close. lol.

Contacting them is just fraught with issues:  

Unless you contact them through some "intended" contact method, you run the risk of soliciting for sex from someone who isn't actually a sex worker, and they can and probably will report you to LE.

I don't think there is a big risk of visiting someone in your own building.  But approaching them without knowing with some certainty that they are, in fact, sex workers, is fraught with liability.

Sure, but I wouldn't let her know where I lived.

Remember the OP is about the guy living in the same building as the provider and not someone that merely lives "nearby." So if you saw a provider that lived in your building, it may not matter that you wouldn't let her know where you live as she might see you on a fairly consistent basis just in casual passing like coming into the building, leaving the building, chatting with friends just outside the building etc. That could REALLY creep her out and she could rightfully think you are stalking her even though in actuality you were not.

on this board you know there is an overwhelming consensus that giving too much personal information to a provider for screening purposes may sound like a good idea initially, but when things go South, all kinds of bad things happen.  If you start seeing them, sooner or later, they will find out you live in their complex, and what better way to get a start on all of your personal info than to google your address and see what comes up? They can get your name and your real phone number (not the burner we all use for seeing providers), and from there a lot more info is available for free and through subscription services.  The question is how much RISK are you willing to take for the convenience of having an incall you can use in your own complex?  For me, these would be the LAST providers on the planet that I would be interested in seeing professionally.

Mr. Lion,  

If the lady has an ad up, fine, answer the ad and let her determine whether she will see you.

Thanks for all of the advice guys! I'm gonna forget i ever saw anything and be on my merry way. I think i knew this was the best option, but i'm glad y'all had the same thought.

I was in a similar situation years ago. I did not hobby back then so I never even thought of pursuing anything. The BIG problem was their clients taking my parking space!!!

What they don't know is best.  Try and find them on a site and then make a date.  Don't divulge that you live in the building. If you run into them after the date just ignore and get on with your day.

So many questions...

I have a similar situation but in my case I am the landlord for two massage girls. Personally they could throw themselves naked and promise me the world and I will walk on by with a polite smile. You are a bit different, If you can easily replace your living conditions at the same or better rates ? I might ask a few polite questions our start a conversation ?      

If they are providers, you will be giving real life information and the ability to make your life miserable if it does not work out.

What sites are they likely to be advertising on?  Maybe start there?
