What are some signs that a therapist may have poor boundaries with their clients?

Session-expressed curiosities about client details not relevant to the therapy.

Disclosing feelings, fantasies, and experiences to the client in ways not related to the work the client is engaged in.

Eager anticipation (or anxious anticipation) of the next session in ways that distract.

Why does it smell so bad? I noticed that when I move around my vagina has a stench. It’s usually a wet liquid, almost like pee. There’re little to no discharge and it doesn’t hurt or itch.

Off the top of my ancient head:

Failing to mention the client in supervision/consultation, out of fear the supervisor/consultant will advise return to ordinary healthy boundaries.

Routinely going over the time limit with certain patients, compromising the time for the next client.

Serious disappointment when the client cancels a session.

Obsessing about clients outside of work hours.

Struggling with fantasies of deeper connections with clients, whether sexual or parental or other intense or intimate relationships beyond psychotherapy.

Why does my vagina smell sort of fishy/musty days after sex when my boyfriend ejaculates in me? There isn’t any itching or burning when urinating, so I don't think I have BV. It just doesn't smell like me.

General Introduction to Boundaries from Panahi Counseling:

These items can happen fleetingly, briefly, in any therapy, but if they’re frequent, it’s definitely time for the therapist to get some good, solid supervision/consultation.

Frequent phoning or texting of clients to “check up on them and make sure they’re OK.”

Why do I feel like something bad is going to happen to me?

Sense of competition with persons who are important in the client’s life.
