Why would a guy fall in love with an SP who has sex for money?
I hope they are smarter than that, she is obviously not to be trusted.
Are you pretending that you understand love? Do you think there is only one type of profile that should be loved? Do you believe that love is only textbook love, or Disney kinda of love??
The first principle for love is not unrealistic perceptions and fake ideas. It is when certain needs or desires on the psychological level are fulfilled. Sex is simply a manifestation of those, it is wrong to assume it as the principle motivator. An SP is a woman, who provide a man with those requirements. Trust is necessary to build a long term relationship, but not for love. Love can be many things. It can be simply intense lust, or an admiration of a certain beauty, a memory of the past, etc...
As for trusting an SP, my personal opinion is that if she does fall in love, an SP is more thrustworthy regarding other sexual encounters than a non SP. In fact, more often than not, they have been there and have tried that, and sex to them is less mysterious than for others. Plus she will train you well to satisfy her, if monogamy is agreed on.
