As far as RP goes, I don't believe in sugar-coating things too much. As long as you keep the material appropriate for the age of the players involved, as far as I'm concerned you can do whatever you want with your characters. Hell, you can make them end up getting eaten by alligators with chainsaw tails after being indecently assaulted by a tentacular platypus for all I care.
However.
As someone who's RPed for years, I've never ERPed, and frankly I feel uncomfortable around people who do. And the reason for that is that ERP is basically porn. Porn doesn't have to be in video format; yes, that really kinky sex scene in that book you otherwise don't really like is porn too. Now if you want porn, go for it; there's a whole internet full of it out there. I doubt you'll have any trouble finding it. But don't come looking to
me to provide it for you. That's why I tend to chose not to do even regular RP with ERPers. I don't like RPing in places where I feel I might need to tell someone "no thanks" about something as intimate as that. If nothing else, some of us are either married or in long-term relationships, and while being asked to ERP might no bother some of those folks, it makes some of the others really uncomfortable. Assume the answer is no; you're not going to offend or upset anyone by refraining from asking them if they want to ERP, but you might by asking them.

This. So much this.
I shouldn't even need to tell you that RPing the act of rape is disturbing, and I can't even begin to imagine why someone would want to do tha -- OK, that's not true. I
can imagine why someone would want to do that, and it's sick. Again,
if you want that as part of your character's story, fine; but put it in a damn memo. Yeesh. As for non-consenting ERP, perma-banning is the only option. Fortunately, that is apparently already against the rules.
I know there are some people who are either deliberately or accidentally going to misunderstand this, and say, "you're so staid! People in the real world have sex, so they should in RP too!" You want your characters to have sex? Knock yourselves out. Establish in role-play that rabbits are shamed by their ardor! Make a point of needing to go to the carpenter every week to get a new bed because the old one's falling to pieces! But if you feel the need to actually
spell out the specific acts, then no, that's just creepy. RP-sex-as-plot is fine with me, but RP-sex-because-I'm-horny is just sad. It doesn't matter if it's not in global; if I know you're the kind of person who is aroused by pretending to engage in explicit sexual acts with a stranger on the server, under the dubious excuse of "it's part of the story!," then you're a creeper! Stay away from me! And if you simply
must do it, there are plenty of chat programs out there, do it on one of those. Or in a sub-forum. (Which would also solve the problem of knowing who's going to be upset by being asked and who isn't.)
In a nutshell, what I'm saying is this: if you want the storyline of your character to include sex, perfectly fine by me. If you think the storyline needs the specifics, then you need to grow up; it doesn't need them, that's your second brain talking. And if you get your jollies from explicitly acting out the terrible traumatizing stuff, you're a truly twisted person.
Look at it like this: in D&D, might I chose to have one of my characters have sex with someone? Depending on the character, absolutely. Would I
spell it out to the DM? No!
