Iīve read rather many articles on this and of course this subject is kind of a taboo as a therapist "shouldnīt" feel this way about a client. A therapist often has more tools than a client to handle such feelings but they still canīt always shut them off. This also exists when the client and the therapist is of the same sex but generally sees themselves as heterosexual.
I wouldnīt want any therapist to tell me about this but I donīt think itīs at all impossible my former T thought of me this way. I donīt mean she actually wanted me but all kinds of people youīve met with might show up in your mind during a sexual situation.
Do you think your therapist is ever sexually attracted to you or has it crossed your mind he or she might see you "flash by" in their mind during a sexual situation?
