It's actually a very interesting question because the statistical data on this is very scewed. What I mean is that when the male therapist crosses professional boundary with the female client, the client is much more likely to report it than the male client would report his female therapist who crossed the boundary with him. So, the statistics of the reported cases doesn't represent the reality of what's going on, and besides that there is no other data about the commonality of the ET in each gender scenario. From what I've read in the professional magazines that regularly publish reports about disciplinary actions, both male and female therapists are being reported, including for sexual violations, but the reports on male therapists seem to be more common.
