If you mean counter-transference in general, every therapist, regardless of gender and other qualities, experiences it and express it one way or another with every client, mostly unconsciously. Counter-transference is just a therapist's transference to a client, and transference is a universal phenomenon that exists everywhere, not only in therapy, including this forum

If you meant specifically erotic transference towards clients, I too would tend to think that male therapists unconsciously act it out more than female therapists. I think, it's just not in the female nature to feel sexually attracted to a man who came to her for help with his emotional issues and his life problems, while for males the opposite is often true. But the cases of female therapists attraction toward male clients do exist, even though they are not as common as with male therapists.
