Men who have had a woman as a Sensei how did you feel about it?

I started taking M.A. lessons a few years ago. At first I felt weird having a woman as a Sensei. A few years later I've come to realize it's just fine. In fact I have come to realize that a woman who probably weighs 100 - 110 lbs. has to be pretty talented to attain such a high level of competence doing throws, joint manipulations to men that outweigh her by over 100 lbs. Your thoughts?
