session 6 with new therapist tomorrow morning. the lifestyle has not come up. when am i supposed to drop it

so i started therapy in feb. anxiety, work stuff, mom dying last year, a lot. she is great, mid 50s, warm, lcsw, not religious from what i can tell, lgbtq friendly per her profile. 5 sessions in we have not touched my marriage in any deep way and we have definitely not touched that my marriage is non-monogamous. session 6 is tomorrow at 8am. heres my problem. a HUGE portion of my emotional life takes place in this part of my life that she doesnt know about. like when i tell her "im exhausted on weekends" the real sentence is "im exhausted bc we hosted a couple saturday night and i didnt sleep much". when she asks abt friendships, the closest friendships i have right now are 3 lifestyle couples we see every 2 months. when she asks abt joy, my biggest source of joy outside my husband is honestly the community. i keep editing my own life into a version of it that fits the therapy room and im starting to feel like im wasting both of our times. f39 he 41, married 12 yrs, lifestyle for 5, very stable and good in it, this is not "the lifestyle is breaking us" content. this is "the therapist doesnt know who im talking abt when i mention friends" content. my fear is loading the bomb. like i show up tomorrow and go "ok also for context im in an open marriage and the lifestyle is a huge part of my world", and she now has to recalibrate everything shes heard for 5 sessions, AND she has whatever her personal reaction is to that. other fear is way smaller but real... what if she has some private religious thing or her own marriage stuff and she suddenly shifts how she sees me. ive read about ppl getting subtly mishandled by therapists who werent kink/poly/lifestyle informed. ive heard horror stories. oh and one more thing she takes notes by hand and i dont know what happens to those notes long term. paranoia? probably. but real. how did you guys do this. did you find a kink-aware therapist from the start. did you drop it casually at session 3. is there a script ppl use
