I am asked this sometimes. When it comes up, I just smile and say "Fine" and change the subject. I do not feel comfortable discussing stuff like that with my guests. The session is supposed to be all about you- not about me! But if you do want to discuss business topics, I will usually change the subject to getting opinions on the way I have things set up. Like "Do you enjoy my website, or do you think it's too much reading?" "Does it make a difference to you whether I have a VIP ad on eros or just a regular one?" ETC. I'd rather not discuss the details of my business in the way of how much I make or how many people I see - but if you want to give me your input on how I made my website or on ad sites and stuff, then I love to get others' input. I know some guys ask coming from a place of concern, but I just think it is a little bit intrusive.  

I'm sure you wouldn't like it if I asked you how much your last paycheck was. Or how much money you have in your bank account. So why should I share those kind of details with you? I once had a friend who liked to hear about how many men I had been with, and frankly it freaked me out so much that we haven't talked in a long time.
