This is really a discussion for the community who is actually going to build this site once it is created, but here's the gist of it —
If this site makes it to beta, it is reasonably safe to assume this site will contain frank discussions stemming from largely clinical questions involving sexual activities between consenting adults. If you are visiting this site from work, you should decide for yourself whether this site is "work appropriate" for your situation.
Essentially, a site about adult activities cannot reasonably be expected to distill all their discussions down to be appropriate for an eight-year-old. If there's the occasional "naughty bit" shown in a diagram somewhere, as long as it's not gratuitous, that should pretty much be expected on a site like this. If that's going to raise an eyebrow where you work, then don't visit this site from work.
I hope it's just that simple.
