Well, my approach would not encompass asking about a man's physical features at all to be honest. This is because I can see a picture of what he looks like beforehand, and see him in person if we meet. This eliminates the disrespectful inquiry about height/weight/shoe size/beard/piercings/tattoos/whatever tf else. If a man has to ask me about my physical characteristics, I can assume he is more interested in a physical relationship. A date is really about figuring out if you two are compatible, and not about how many arms and legs someone has. Similarly, if I was interested in just a physical relationship, then I might wonder about his six pack or what have you, but I would not ASK about something like that, because that is simply inappropriate. You really should wait to MEET someone and SEE what they look like to avoid confronting them about appearances and etc. It's just a matter of formalities and showing respect for others regardless of their gender.
