you were a victim of censorship and the sexual content you refer to would also be censored by other people , perhaps people that feel exactly as you do. I believe that steemit has handled this situation very well through being able to "mute" and "flag" and therefore self regulate.
You are right that some people might censor, but I would rather not look, than repress. On steemit, I just unfollow if I don't like the content. Something would have to be on the level of chid-porn for me to use the 'flag' option.
