Correct. I have no idea why people are freaking out over drinking water. We constantly eat and drink things that have wildly different osmolarity than our cells and yet here we still are. Our stomach and intestinal mucosa cells are not going to burst if we accidentally drink a milkshake (a hyperosmotic solution).
polyamory is an alternative to monogamy, so if you think a community about monogamous relationships should be NSFW then I guess, but I think that might be a stretch.
