Behaviour in the OOC

It has been brought to my attention constantly about the contents and context of most conversations in the OOC room.
There are currently no filters, but it seems that some of the more sexually-related conversations are rubbing many people the wrong way, despite them being made in jest. Too much of it isn't all that funny, and... its been a large factor in why some of the new people who register for the site do not return. So, my question, are we able to clean it up a little, or will I have to put in word restrictions, and enforce more rules upon the site? I don't want to, but if all our conversations are driving people away... Theres somthing wrong. Suggestions?
