Well, I see myself in several of those categories but believe "Man With A Plan" fits best. Always looking for best bang for the buck and to avoid the drama associated with real-world ladies who look to attache strings. So far, I have been having lots fun with many ladies and will keep this up until the well runs dry.
I am also a little bit of a "Sex Addict" who needs to have wide variety of hot ladies. Yes, I spend way too much of my time on eccie and other boards doing research on the next best thing. I always have at least one or two sessions lined up so as not to miss a single opportunity to hobby with a hot lady.
I also find times when I could be called a "Strange Pounder" in that I am often enjoy unique hobby experiences: Anal, spinners, squirters, restraints, trips to another realm, two/three lady sessions, and of course lots of DATY/DATO and Multiple Positions which are not available otherwise.
I think above qualifies me as a fully certifiable ManWhore.
WRT the other categories:
I can't see anyone wishing to publicly categorize themselves as an "Adventure Seeker" with all the associated drama;
Admit to being a "Crazy Asshole" though I know they are out there; or,
See themselves as a "Hormone Crazy" guy who is falling into a deep chasm of guilt and disappointment; and,
I know there are "Pitiful Losers" out there because we see daily board discussions and guys bragging about their adventures when many other guys just simply shake their heads in amazement and wonderment--guess there is somebody out there for everybody.
Man With A Plan, Sex Addict, Strange Pounder, Adventure Seeker, Crazy Asshole, Hormone Crazy, Pitiful Loser... What kind of Hobbyist are YOU?
Just Kidding--couldn't resist the temptation, which is my big weakness with the hobby.
