i completely understand what you are talking about. i'm similar in that i didn't entirely sexualize people I liked. I mean i couldn't help but recognize my sexual attraction to them but I didn't think about sex with them as opposed to how i could get to know them
I think it just shows that you don't see women purely for the sexual being then can be but more the human being they are
Don't worry about it, it ain't bad. It's good to get to know them before creating a fantasy about them that won't be representive. It might be bad once you really get close and you don't feel like you ever want to have sex with them. So for now calm down and don't worry, nothing wrong with you. Everyone treats crushes different so there ain't really a good/bad way.
Yes, sex is not degrading. At all. There's nothing wrong with thinking about sex and how sexy and attractive you find a person. Thats part of liking people. Obviously you should focus on getting to know them too, but your view of sex seems too... uptight. Girls like sex you know, and girls like it when you want them sexually. Emotionally too of course but don't think of it so seriously.
No, it is not bad - if anything, in my experience, it's good :) It means your feelings for them are genuine and a relationship with them will be easier to maintain as you won't be dying for a BJ every two seconds
