Is this a red flag?

I’m looking for a CSAT for my partner. I have a specific therapist in mind, but on their Psychology Today page they also have sex-positive, kink allied, and open relationships non-monogamy under their specialties and expertise section. They say that they are sex worker aligned as well.

I am fully in support of anyone that is a sex worker and I am in support of any type of consensual relationship for other people, but my partner and I are interested in a monogamous relationship with a no porn boundary. Is this a red flag?

The therapist uses the task-centered Carnes model and earned their certification under IITAP.
