the definition I could find on tri-sexual was;
http://en.wikipedia.org/wiki/Trisexualbasicly, it gave it five basic meanings;
* someone who is sexually interested in transgender persons in addition to cisgender men and women
* someone who is sexually interested in men, women, and oneself (autosexuality)
* someone who is sexually interested in men, women, and animals (bestiality)
* someone who is sexually interested in men, women and vegetables (lachanophilia)
* someone who will try any sexual experience
if thats the case, then I suppose I fit the definition, under the 5th meaning
but I dont really see the point in the term Trisexual, it seems like more of a blanket term, y'know
