Yes it is certainly a matter of personal preference. I am in my natural state and have a very distinct preference for men that are the same. Generally, I find something distinctly unsatisfactory about the circumcised penis. Of course there are those occasions when one has to make an exception, when the man himself is very nice, and that of course is the most important aspect.
I shave and not because porn stars do it. I first shaved my pubic hair when I was 16 and didn't even know about porn stars then. I prefer my penis and balls to be smooth. I like the look and feel and I like seeing other men (and women for that matter) shaved too, or certainly trimmed. Even though I am blessed with big balls, no, they do not get stuck to my legs .... So this has nothing at all with 'being a man' it is just personal choice.
I once had sex in a gallery in the Victoria & Albert Museum in London. I used to live near a wild area of trees and bushes and I often went there and had sex or if there was no one that wanted to play I would just get naked and masturabe. What I would like to do is make another visit to the Folsom Street Fair, be naked and masturbate while people are watching or passing by.
