I've got some girlfriend with very closed mentality about sex, and I've got some girlfriend very open minded, but I never had a girlfriend with the same nasty attitude as you can see into a Miko Lee, Tia Ling, Sai Tai Tiger or Nadi Pukhet movie's.
We must realize that in our ordinary life sex is much more boring than that you can see in the show business, where everything is deliberately exaggerated and spectacular, and at last that which distinguishes a best porn star from a bad actress its to be able to make everything most realistic.
I have never EVER found sex to be boring with any woman that I have ever dated...if anything, sex was always the highlight, and we eventually parted ways for other reasons....I think perhaps because I am somewhat of an open minded person, woman pick up on that, and they never hesitate to show me thier sexual wild side because they know I won't be phased by it or judge them negatively...Alot of guys aren't like that...if they see that thier girlfriend is too freaky, then they are turned off by it because they consider her a whore, slut, or some kind of sexual pervert...Who knows...some of your "signifigant others" maybe more kinky than you think, but they don't tell you because of how you might react !
In regards to porn, I have found that in general, my personal sex life has been way more interesting than some strippers, porn actresses, and escorts that I have known...It has been my experience that the woman I have met who work in the sex industry sometimes have issues that other girls don't have...because they have sex or get naked for a living, they often think that this is all a man sees them for, and so they can be somehwhat jaded, or have somewhat of an emotionally distorted view of how to trust a man, and how to be sexually uninhibited with a guy that they actually care for...but those are just my experiences, and I certainly don't mean to over-generalize, because I'm quite sure that there are many adult models that don't fit that profile.
I do agree that the best pornstars are those that can give the most realistic performances that are also hot. But I don't look at my personal sex life as being boring as compared to theirs just because of what they do in front of a cammera. I'll admit some pornstars have done things I have never done, and probably never will....but under NO circumstances have I felt like having sex with ANY woman was boring...Nor have I ever been called "boring" by a woman,,,I guess you can never really know with absolute certainty how another person views your sexual performance,,,but I've always felt like I have led a very vibrant and fulfilled sex life...I wouldn't change a thing...Just much more of the same !
