a sex positive yoga retreat that's sort of LS-adjacent... is it our thing?

theres a retreat company that does these long weekends in cornwall/portugal/canaries - tantric workshops, partner yoga, very body positive, optional nudity, sex positive vibes, but its not technically a swing event. some couples open up during it, some dont, and theres apparently a lot of grey zone. ive been wanting to book one for ages, wife is interested but unsure if its going to be too "spiritual" for her... is anyone actually been on one of these and can describe what they're like in practice? especially the bit between the proper retreat structure and what happens in peoples cabins after
