Why the fuck do you care about the percentages that much? And why on earth would it bother what online strangers in cyberspace, whom you're never going meet, write down about their sexuality percentages? Does gayness have to uphold a strict purity level of 100%, and if we fail to honour our oaths to uphold that purity (taken with solemn vows in front of gold spray painted model representing Adonis), we are thereby invoking the wrath of the gay gods?
I put 99%, primarily because I like the look of the number 99. But I also suppose my reproductive capabilities could be brought into use should there be a near global mass extinction (though I would need to overcome my tendencies towards misanthropy in that case), I do not fall in the "yuck, I just saw a va-jay-jay" camp (my policy is va-jay-jay neutral and non-sexual) and I occasionally kiss female friends when drunk. However, my experiences and fantasies are exclusively gay. Is that bisexual? Umm, no. Don't really give a fuck if you think so though. Does it matter? No. Is gayness a competition in my opinion? No.
All those stated sexuality percentages actually tell you anyway, is how a person wishes to be perceived. These can be accurate, but often aren't.
