I can say this: When I was a kid, I knew about penises, vaginas, sex, ect (mind my language). I wasn't bothered by all this. And I think I can say the same for all of the younger audience in LOTC. We aren't all 5 years old, we can handle sexual things. If your feeling uncomfortable by RP going on, just kindly ask the guy to stop, and he should be mature enough to do it. I think you should have more faith in the maturity of this community. We aren't babies. We've all heard swears, know about genitals and all that. It's not that big of a deal.
As for violence, I think that is completely absurd. Characters like Knox are what would be seen in a horror movie. Now, I think we can all agree with me, as a guy generally not liking gore at all. What is scary to us about gore? Actually seeing it. I will be more disgusted and scared if I see blood coming out in a fountain from a guys body then if I see one of Knox's emotes, I will probably just say "That's gross" in my head and walk away. Again, we aren't babies.
People can be more sensitive about sexual things, of course, but I think most of us are mature enough to deal with it.
