My thoughts on the survey... They're trying to link porn consumption/sex addition with animal attraction, which is fair enough. Anecdotally I've heard people say they saw a dog fucking a hot girl and were immediately addicted, etc. However, I've been a zoo since before the internet (ya, get off my lawn, kiddies, lol) so that doesn't really track for me, but whatever.
My main complaint with the survey is that there is some vagueness in the questions that conflate humans with animals, and also a lot that conflate CURRENT self-acceptance with acceptance when seen from the greater society or seen from the past. That is, questions like "have you ever tried and failed to stop a sexual activity" (not exactly a Q in there, but as a similar example) would be answered differently if I'm thinking about how I feel personally when I have a butt full of stallion cum today, vs. when I was a teen and was unable to deal with my wacky animal attractions and was desperately trying to stop having these thoughts.
Basically, at some point I realized that I couldn't reprogram my brain and I just ran with what hand I was dealt. Didn't like it particularly, but what can you do, I reasoned? Anyway, that subtlety is lost in these questions, so my responses look a bit all over the map because in some cases I'm like, "ya, I'm comfortable with who I am" yet other answers are like "fuck ya I am stressed about what other people think about me because they can destroy me!"
Also, there are all these "who is to blame if you have sexual problems" and that whole phrasing is just odd to me. What kind of "problems"?? As in, my partner doesn't want sex? That's not a problem, that's life: It's a partnership. So do they mean sexual dysfunction as in impotence??? I'm totally confused by all of those (rephrased like 10 times) questions, and had to choose the middle option because I didn't know wtf they were getting at.
Anyway, every study pushes the boulder of knowledge a bit further up the hill, even if they are imperfectly designed studies.
