Most people consider sexual perversions to be something that other people have to be ashamed of, or something that should not be talked about, or something that must be banned right away. However, this is not the case. The majority of sexual perversions that real people experience have nothing to do with anything ugly or dangerous.
If to think about it, many things that today are considered within the borders of the norm, or just somewhat weird, were believed to be awful perversions in the past and the people were punished severely. Lesbian sex is a good example. However, today, it is generally believed that any perversion that brings no harm to other people (or creatures, like animals) may be weird, but overall accepted.
