Two things.
1) I'm totally naming a captured Berserker in my FWL force 'The Ugly-Bumper' now.
2) It's sound advice, what five_corparty has there. If it's going to be sexually explicit stuff, it's probably best to trim it from the version posted here, at the very least. I know that's not something fun to do to your work (there's nothing I hate more than trimming my own writing, just in-general!), but these being the official forums, we do try to keep things pretty PG-13. If there's anything to be said about the internet, it's that there's no shortage of places to put explicit content- but this might not be the one.
The other aspect on that one is that the mod and admin team are all volunteers, with busy lives away from the forums. While asking them to take a few minutes to review a fanfic for sexual/overly-violent content doesn't seem like much at a glance, having dozens of people making those requests adds up fast. I cant ask the mod staff to be editors AND moderators, as you can imagine.
Long ago, I read advice from a former mod here saying that the line is varied, but the best way to look at the line of good taste is 'would I show this to my mom?'. Everyone has different mothers, of course, but you get the idea- if you have stuff in there you wouldn't want to show off to family, it's time to break out the 'delete' button.
That said, I do thank you for asking first, and I do look forward to seeing a less-genitalia-ed version of your work.
