Attention ladies, please participate in my scientific survey

I was wondering if having tattoos or piercings is a good indicator that a woman enjoys masturbation and I realized that I can answer my question using Bayes' Theorem:

P(M|T) = P(T|M) P(M) / P(T)

where

P(M|T) is the probability that a woman masturbates, given that she has a tattoo. This is what I'm trying to find out.
P(T|M) is the probability that a woman has a tattoo, given that she masturbates. This will come from the poll in this thread.
P(M) is the probability that a woman masturbates. Several studies have already attempted to find this number.
P(T) is the probability that a woman has a tattoo. I'm sure I can find the results of a survey for this.

The poll stays open for a month. I will post my results when the poll closes.
