I feel Romance and Sexual Content are polar parts of the brain. So those who enjoy romance often, not always, don't enjoy sexual content (and the vice versa). If that is true, the group of people who enjoy romance really dominate what is acceptable in society. You can put a romance media down really anywhere (tv pretty much anytime) but ... raw sexual engagement? Well that is utterly unacceptable but in the dark corners of the net. Of course, that opposite brain thingy really reacts in the same way (censorship). Interesting human behavior is all.
