I have a different understanding about the question. So, I'll just go ahead with my own thought on this. (I'm classy anyway). lol
If the ones who has a crush on me ask about my other crushes, that means she wants to compare herself against the ones I'm crushing over.
Yea. It happens.
One time, she asked me if boob size matters. Well, I just said,
"it's up to you how you work with them. There are tons of ladies who still look attractive even if they are less than B cup. It's all about charisma."

She said, "I see your whatsome bhebs group. How about the likes of me?"
Me: "Hey, baby. I like chongas too. Don't worry. I know I get weak-hearted when I see ladies wear sexy librarian glasses and nice bowl hair cut. But, you still have a shot. :)"
