Taboos and Sexual Arousal

This is a graph illustrating how sexually aroused people get thinking about certain taboos.  I found this on Reddit, and it appears on the subreddit /r/dataisbeautiful (clicking on the above image will take you to the imgur original, which is much easier to read).  There's an enormous amount of information here to process, but there are a few things I wish to comment briefly on.  

First of all, the top taboos for men:  group sex, performing sex acts with a friend, and the two age gaps: having sex with someone at least ten years older and with someone who is an adolescent.  Incest is up there for men, but is only half as arousing for men as adolescents.  What do we glean from this?  That we need to rethink how we deal with men and the taboo of sexual attraction to adolescents.  That it's probably even more common of a fantasy than this graph indicates?  

And for women?  I think the results for women are even more interesting.

The top fantasies for women are BDSM, group sex, sex with a friend, and sex with someone older.  What should be noted are the high numbers of women who also are aroused by rape and being strangled.  That women, and not men, have more sexual fantasies about violence is fascinating.  Twice as many women find rape as arousing as men do.  Why is this?  It's possible it's an exaggerated metaphor for power and masculinity, of finding release and freedom in subordination and slavery.  

What surprised me is that group sex, sex with a friend, or with someone at least ten years older are considered taboo experiences.  I had no idea that my life has consisted of breaking one taboo after another.
