Has this hobby changed your taste in women?
I don't think the standard human mind is capable of giving you a scientific answer to your seemingly-reasonable question.
It is more sensible to observe that
this hobby represents a variety which very few men can expect to know outside of such a setting.
In the same way that FAR too many
second wives OR
second girlfriends remarkably resemble
first wives or
first girlfriends... it is highly probable that the standard human mind
will never encounter sexually enough authentic variety to develop a personal preference free of bias or outside/in-authentic influence.
SO you take the average schmuck, who once thought he'd make a go of it in standard social circles... and he did, for a while... and then things got
complicated...
Maybe he broke-up with a long-time lover... and waited a while, and when he regained his confidence, and went back out there... he really didn't know HOW to select a next partner... but he knew he tended to lean toward those who matched what he
knew for so long... and soon he found himself
nearer TO many women who fit that same mold... and presto, the next time he entered into a long-term relationship... she bore a strong resemblance to that first lover.
Well, eventually, enter prostitution... and suddenly, he can
socialize with the strong (confidence) that
everybody will say yes to him...
And suddenly, he's there in front of the candy counter... in awe of all the flavors... and still with no idea how to select one for his first encounter
He probably STILL goes near to what he knows... because he, and most humans, are likely wired in just that way.
But eventually, greater awareness of the vast
numbers of possibilities draws him toward experimenting with all sorts of looks... yet it still isn't fully
random enough to where any pattern had once been freely-enough chosen that he could be said to have came in liking one
type of woman and evolved to a strong preference for another type of woman.
There is just too much
randomness all around to let yourself believed that anyone
changed anything
as if steering a motorboat in a different direction.
Add lots of
randomness to earlier
randomness and indeed a lot of
random things will likely transpire... but that doesn't mean you were in as much
control over it as you'd like to think.
