I am not even sure how to answer this, I guess because I find the questions in your original post a little confusing.
Basically, I think I see emotional attractions as friendships and sexual attractions as sexual partners (or potential partners). I am able to see things about friends that I consider sexy, even though I know I am not drawn enough to them to go there myself. And lots of different elements go into what makes someone sexually attractive to me. It's not just physical, but personality, humor, intellect, and so on. Then I think there is a hormonal thing, like pheromones.
I suspect that your perspective on these attractions may very well change for you, Ray, after you've had sex.
The world opens up... when you do.
