I'll assume that you are a fairly young guy (early 20's) which I can see a 40 yr old being a bit scary. A friendly piece of advice though, is don't judge a book by it's cover. Many a super hot MPA hasn't lasted in this business very long because all they offered was their looks. You can get tired of a hot girl really quickly, or in otherwords, after only 2 or 3 sessions. If someone has been around for awhile, and has good reviews, it's for a reason.
