Don't want to get into tired arguments about simps and gentlemen, whatever those terms even mean, but to keep this perhaps substantive and productive, let me ask this, why is it when sex is involved, this is the course of action?
What I mean is, is it about anger, from rejection? If you have a business meeting, an investor, a client, whatever, and they reject you, lets say a casual setting like a hotel lobby, or whatever, or your place, do you order them out, instantly? Or do you want to keep the contact, or at least make yourself look good, for reputation sake, if nothing else? Or does one also understand that not ever business deal is going to work, and not everyone is going to invest with you, for many reasons?
Sex is also deeply personal on some level, while business may not be, but why is it so different?
