Boundless Universe! BU-RP! www. roleplay-bu.com. It has a forum but the roleplay is mostly done on site, I do believe they are 16+ Its medival fantasy and CLEAN! No yiff. Its not furry based its magic based and human based. There are some anthros and weres. But if you are into some cool stuff with that check it out read the rules, there rp chat is really set up nice and the players are VERY welcoming. Check it out and tell me what you think.

Feel free to explore those :D
This one one I havent been on for a long time but I still feel that I should do some PR for them too. A place called fantasyrole.org ! They have a great lay out and it looks amazing! They are a forum based RP site focused on fantasy (again I know) I have made some friends there was well and though I havent been on in the longest time I still found it comfortable and fun especially if you are looking to start forum posting. Its for most ages I am not sure about their rules I think this is a place to be explored.
So go exploring guys :D Please go check these out!
