There is no way to know unless you speak with her; if she is well-trained and ethical, she will WANT to discuss it with you and straighten things out; IF she was indeed being seductive (and isn't honest and ethical) then she will deny it and confuse the situation. You are paying for a service and deserve to be treated with dignity and respect. There is a good book on the subject: Sex in the Forbidden Zone by Peter Rutter....it points out seductive behavior and is very eye-opening when one is confused as to what is happening in therapy.
