Rated G for gangster

On PC, RPs go by a rating system, so there is some indication as to how rough and raunchy a roleplay can get.
We have K, K+, T and M, with K being completely child friendly, and M being mature as hell. In what rating do you like to play? Do you enjoy the adult themes an M rated roleplay can bring over a K one, or do you tend to prefer the safer rating of K over it's raunchier counterparts?

I prefer M. Titans was T and at times in my writing process I would get something made and then think for a second, remember that it was rated T and then go back and completely erase it. Idk, I just don't feel as comfortable playing anything besides M.

I tend to prefer M to the other ratings, although I'm not uncomfortable playing T. I feel like I'm walking on eggshells when I try and write K rated stuff and I tend to think there's a lot more room of creative freedom in the higher ratings.

T or M for me. I'm sure that you can be creative with lower ratings, but I find it difficult. Most standard pokemon roleplays could probably fit under K, but I find those to be generally boring. I think that creative concepts usually require a higher rating.
