I agree all the providers do it for the money and fake it because they are tired of doing that many guys a day. I wonder if the providers will ever find love or in a relationship with men after doing this work?
When you see a gal who suddenly becomes demure and more self-conscious at follow-up sessions - perhaps they have a slight thing for you.
When you have a well documented spitter swallow your semen and cuddles up to you without running for the Listerine - either she has a fondness for you or your deposit tastes good, but most likely both.
When you have a gal switch from the Crown to the Sagami - perhaps she wants to feel closer to you while still playing it safe.
When you have a gal on repeat visits who no longer suggests a shower before the session - perhaps she wants the interaction with you to flow more naturally (and she knows you'll always be clean as a whistle in her presence).
When you have a gal who passes you along to all of her gal pals - Then, maybe she thinks you're a good lay, but nothing serious will ever become of it.
When you have a gal who passes along her number on the first visit - Either she thinks you would be an easy/ pleasant regular, she smells money, or maybe she thinks you're a good catch.
When you have a gal that hints at meeting for coffee to get to know each other better - Perhaps the interest is real, or perhaps it's the beginning of a long hustle.
Whatever the case, behavioral cues should be assessed in clusters to derive plausible conclusions - but as others have said, dating a companion is probably the quickest road to Hell.
