We are told, that too much of something is never good. Even if the something itself can be considered "good". Now that framing of good and bad, is something that is able to change during how society evolves. Kind of like movies are able to not just show nudtiy, but go completely off the rails ... if you thought other movies are explicit ... well you haven't seen this yet obviously.
Now let's make this clear: this shows penetration and sexual acts. Some will (rightfully) call it porn. At least the uncut version (apparently there are versions of this without all the sex - which must make that version a very short one), have not seen the other one and how it fares. If you are sensitive, this is not for you (and the ending tries to top it all off ... as if we didn't know that character had some issues overall)! While putting so many people in one place (to supposedly "cure" them), with many sex fantasies, may not sound like the best idea - it is necessary to have an excuse for all the ... fornicating/sex acts.
There is a lot of comedy, some expected and unexpected turns (do you think the woman who is rigid and decries any sex and calls herself asexual, will find any liking at last in the act?) ... overall some may think this could have done with less or none of the sex elements - the very in your face (or other places) scenes that is ... maybe, that is up to you to decide. The human psyche seems crazy and the problems seem real, even if very convenient to assemble a group like this ...
