Is it normal that i judge someone's sexual attractiveness by asking myself this?

So, most people - when dating - have kind of like a checklist of all the attributes they find physically/emotionally attractive in the demographic towards whom their sexual orientation is directed at.

But I, instead of having a height requirement or desiring a good waist to hip ratio in the women I choose to approach, judge physical attraction alone based on how badly I'd like them to fulfill my sexual desires...

So like if I saw a girl walking down the street, instead of thinking "wow, she's got a really cute face!" or "check out the legs on her!", I'd be thinking like "I wonder how it would feel to get choked out by the biceps on that woman?" or "what could be more sexy than a private dance from the lady over there?"

I'd never say this out loud, it's always an internal thought process, and if I approached her that certainly wouldn't be the line of questioning I'd use to get to know her, of course...

That being said, however, that is the spectrum I use to guage how physically attractive they are from a distance. If I don't think i'd enjoy her fulfilling my sexual fantasies, I don't approach.
