Is the practice of having sex with a friend of the opposite sex in good taste? Is it appropriate considering that a friendship is supposed to be platonic?

It’s in good taste if the people consenting to have sex with each other agree that it is in good taste.

Everyone else not having consensual sex in this arrangement has and deserves literally no say in the matter. People are never obligated to get community consensus for their private affairs.

If you’re surrounded by a bunch of judgmental busybodies and naysayers that will give you shit about it, agree amongst your FWB selves to keep the arrangement and details private.

If you’re not sure you and your potential FWB partner(s) indeed have an FWB arrangement, read this article. Again, this is for the people involved to determine, not outside observers (“the community”).

Happy FWB’ing.
