Yes!!! Excellent analogy! I also like to give an analogy regarding hands:

I like looking at men’s hands. I notice how long and thick their fingers are, whether their hands look clean and their nails well-kept, etc. I definitely think about fingering, and I certainly love me some fingering. I am assessing men’s hands sometimes for this, without them having any idea. Hands can be used for penetrative sex. They are, therefore, a “sexual” body part. Why don’t men cover their hands, in that case? They shouldn’t be flashing their naked hands about, since hands are a body part that people look at and think “sex.” It’s provocative, vulgar, in poor taste, un-classy, etc. for men not to cover up their hands.

You get the idea. ;)
