TBH all you really have to do is recognise that this is not the way to a relationship, but it is the way to great sex. Choose well reviewed nice girls and treat them respectfully. Then, if you connect, you can really love your time together, in the moment, done right it can feel very real. However, as warned elsewhere, and very particularly for a single guy you have to watch out for EAS (Emotional Attachment Syndrome). The last thing you want is to get a knot in your stomach and read something into your relationship that isn't there. TBH that will only P155 off any service provider. You declare your undying love, or try to limit, control or manipulate her and she is likely to get angry and tell you to take a hike.
Believe me this is absolutely NOT the drug needy, seedy underworld that it is usually portrayed as, - I'm not saying that this element doesn't still exist but the internet has totally transformed this industry. Service providers are, in my Adultwork experience, very often, beautiful, clean, independent, and usually younger ladies purveying the most erotic of sexual fantasies. It's a dream world more than an underworld. You pay for entry, have delightful fun and leave.
Now of course the other thing these ladies will usually have in common is a high libido, they need to be highly sexed otherwise this would be very difficult for them. So imagine for a moment that you end up in an exclusive relationship with them. It's one thing that many women eventually want little or no sex in a relationship (scientists now suggest that reason for dwindling libidos is apparently food stuff related - Wedding Cake!). So imagine being in a relationship with a woman that wants sex multiple times a day, every day, week in week out? TBH this hasn't ever happened to me, but it did to a friend of mine and eventually it was too much for him and they separated. I'm not saying a relationship between SP and SS cannot ever have a future, but don't go into this thinking this is a way to meet your future wife. That's the way to certain disappointment.
The other thing is, due to those earlier mentioned preconceptions about what this industry is, that this life is secret, for us as punters and for the providers. Very few people on either side risk sharing the fact that they do this with anyone else. I may, could even be 'probably', have real people friends who do this, but I've never shared it and I expect they never would either. So it's your secret and unless you have designs on say becoming Prime Minister or something high profile like that, if you're careful nobody in your personal circle need ever know.
One glorious potential upside to add though is, if you start having good positive meetings and find they're mutually pleasurable your ability and self confidence will probably improve whilst your desperation to meet (fuck) a girl will decline, both latter factors are more likely to make you appear more attractive to the fairer sex so it could improve your chances. And if, in the real world, you start a genuine relationship then you just quietly stop (or not) meeting working girls. If you've kept it secret from everybody, who else needs to know?
