In my younger days, it seemed somehow important but now, I just don't care. That may be because when we are young men, it is part of the peer pressure or programming to be concerned with such things. I'm not sure but now that I'm older, I try to think of each sexual encounter that I have as something unique and leave it as just another fun experience and connection to a fellow human being. Nothing more, nothing less. I remember some encounters vividly going back many years and some have been completely forgotten. Just like many other things in my life.
