A few of you have alluded to this, but I will state it directly.
Good sex is much more just physical appearances.
To be sure, the visual aspects are important, especially at first. What I mean about at first, are the initial impressions. There is no denying that an attractive face and a nice body immediately stimulates the average person into thoughts of carnal pleasure. I doubt that anyone is immune, well at least I'm not!
That said, especially after the first few times, it takes more, at least for me, to keep interested. You notice in many reviews, the GFE, girl friend experience, is rated as extremely important. I'll have to say, this GFE, is most of the time a fantasy girl friend experience, since a great percentage of players, actually are not that experienced in the realm of actual relationship that last long enough to be considered girlfriends, but hey, that's another topic for a thread.
This GFE consists primarily of the comfort level felt by the man and that's where personality dominates. It's the difference between a merely physical encounter and a more comprehensive one that reaches a higher level of satisfaction.
And... as a further plug for our lovely TAG ladies, that's why they are on a higher level than the average encounter!!!
