Well I can't say there was any single defining moment that pointed me to that conclusion. I think the reason I identify as such is because I don't experience the attraction normal people do. Like the way I see it people have a much easier time getting together than me, which might explain why sometimes when I read VNs that have characters getting romantical so quickly it urks me because I just can't understand relate to them. Most often I won't really jump into a relationship or even feel comfortable with it until a long time has passed and I've gotten to know the person really well and even then sometimes there is just "no joy". I don't really experience the sexual or romantic feelings for a person, that isn't to say I wont tease cuz apparently I am a very big tease, but when the intent to actually do something is present I just don't feel it. But I digress, I guess to answer your question, I think the moment I realized I was demi was when I just couldn't do the hook up thing with other gay men. It just felt wrong cuz and uncomfortable no matter how "hot" the guy was. That's also another thing... I don't normally find porn all that interesting. Most of my reactions to it are like... that's neat thumbs up... lol
