I started out 99% straight, 1% gay because I have absolutely no interest in an emotional connection with men. In other words I agree wholeheartedly with theaussieone's Gore Vidal quote and have always felt that a person's sexual orientation should be based on that which we cannot choose or easily change; i.e. whether or not one can have an emotionally fulfilling, loving, caring, sharing, life partner of either sex (bi), same sex (gay) or opposite sex (hetero).
But then I found myself being flamed by any number of gay members of the site as having an identity crisis, not knowing what the f**k I was talking about or being in denial. So I changed my percentage to 80/20 since I do have a strong interest in enjoying sex with men, it just doesn't extend to all the huggy, kissy, hand-holding moments that I can enjoy with a woman. And the flaming comments and messages continued so I finally adjusted it to 60/40. So the end result of my four years' membership at LPSG has been the realization that labels suck and we'd all be better of not using them at all. But it's human nature to want to pigeon-hole people into neat little categories where they can be thought of in a prejudicial way. That's a helluva lot easier than having to think and working to understand the individual. So I guess we're all stuck with the labels.
The only reason I haven't followed theaussieone's lead and simply deleted my percentages from my profile is because I now view those self proclaimed percentages to be a fun part of the LPSG experience. I really enjoy reading the member's thoughts and posts and then speculating on just what their percentages mean to them, individually. As was pointed out by the first respondent to this thread (ManlyBanisters) it means different things to different people and I find it is fun to speculate on what those numbers show about the member's view of sex acts, relationships and orientation.
