Poor tripod, everyone's criticizing his list. I was with you on the first two, but the rest reads like straight guy's misconception of what gay guys are into. Many gay men don't care for, or are indifferent to, body hair and facial hair. Not all of us are into anal sex. On the other hand, there are some straight men who are into anal sex.
However, I think you've generally got the right idea, you just need to simplify it a bit. Gay men are, in a general sense, attracted to men, not just their bodies or specific body parts, although that's a part of it, but to the whole man. It's a desire to bond emotionally and spiritually with another man and all the gestures of intimacy and affection that come with that (e.g., kissing, holding hands, gazing into each other eyes, snuggling together, having a romantic dinner or picnic, etc., etc.) and just wanting to spend time in the presence of another man who feels special to you.
I imagine straight men can form strong emotional attachments to other guys and want to spend time with them. I think the key to being gay is having a particular desire for both sexual and emotional connection to other men, without having similar desires for women.
I feel somewhat badly for straight guys who are turned on by dicks, whether they're big or not, or of a particular type or not. First, you have to go through all this questioning of your own sexuality. Then, if you admit to anyone else that you're turned on by cocks (especially if you want to do more than just look), then other people are going to wonder about your sexuality as well. Either you have to live with your desire/curiosity unfulfilled, or you have to find someone who is willing to indulge you without expecting more from you, and a female partner who is willing to let you indulge. This is no easy task. If it's something you want to do more than once, over the course of a lifetime you'll probably have to find several guys willing to indulge you.
Anyway, I don't know if I'd go as far to say that all guys feel this way, but it does seem to be a fairly common "fetish," for lack of a better word. (On the other hand, the straight male members of lpsg may not be representative of the larger straight male population.) I wouldn't even classify this as bisexual, although some guys who feel this way may choose to identify themselves that way. Since the word "bisexual" seems to mean something different to everyone, who am I to say? Then again, some straight guys will, under the right circumstances, do more sexual stuff with another guy than any bisexual-identified guy ever would. (Heck, there are straight guys who have had more gay sex than I've had. It's sad, really.)
