I do think that manga and anime have done much to desensitize me towards violence, profanity, and nudity. At least when it comes to watching other manga or anime. For instance, I remember being really freaked out when I guy lost his head in Black Cat. Now, I can read JoJo and Blade of the Immortal without feeling uncomfortable about the way the characters are maimed and killed.
This desensitization does not carry over into other forms of entertainment, however, which is the funny thing. While I may watch higher content films now that I am older, I think this increase is because of my relative maturity level rather than desensitization due to anime and mange viewing. Violence still bothers me, especially if it is of the usual horror kind such as torture or against women and children.
