This community, I think, will serve you well. It adheres to a good variety of roleplays (and actually, sexual/erotic is heavily frowned upon and suggested to keep in PM's for the most part, or simply "fade to black", so you won't have that problem here).

So long as you think you can adhere to the basic guidelines to each forum and the roleplays of specific GM's in the advanced section, you should be able to hop in there just fine; the community is pretty open to new users. Just make sure you make a good impression in the CS, at least. I'm not particularly old around here and I could jump into an advanced if I wanted to (although I opt in the side of casual and free for the most part).
