I have never and would never invite a WG into my home. Let me explain why I think to do so would be foolish.
Regardless of whether you are single, married or co-habiting, any WG is a pro. She sells sex, seduction and satisfaction for a living. Lying (or acting if you prefer), are part of the job description for a WG. That is not a criticism, it is a fact. The more honest ladies would agree and accept that what matters most is not to convince a man he is anything special, but that he might just be special enough for them to actually enjoy their 'work'. Now, that's not to say some girls don't enjoy their work - they do. But true enjoyment is like real-life chemistry: it is both infrequent and elusive.
I have had occasions when the lady I am with has successfully seduced me into believing I am her lover. I know I am not and could never be. But her 'performance' is so utterly convincing as to warrant very little doubt. The key thing to always bear in mind is a simple one: savour the moment and the delicious aftertaste. Celebrate it. Reminisce about it for hours, weeks, days or years. But never forget it was just an interlude in the mundane reality that is life without regular sexual activity.
Perhaps more importantly, you will always get a better understanding of how any girl 'really' is when you enter her environment. This is particularly true if she lives where she works, as a majority of girls do. Yes, a girl will generally feel more secure and self-confident in her domain, but the reason an incall to her place is best is that you are putting both her skills as a hostess as well as a sexual partner to the test.
In other words, she is the one who needs to create the environment that is both welcoming and stimulating whilst you need do nothing except graciously accept her hospitality.
In my experience, the ability of a girl to perform as hostess is often a superb indicator of her ability to convince you that you are her one and only focus whilst together. All that follows is usually as good as it can be - often as a result of how relaxed a girl can feel after seducing you with her skills as a hostess.
