I have a pet hypothesis that, on average, those into step porn are more likely not have grown up with a sibling of the gender they fancy. I reckon those of us who did are more likely to repelled by anything alluding to incest.
People who grew up with ACTUAL hot step siblings notwithstanding.
You should do a poll, if you get enough comment responses to be statistically significant it would be a pain to sort through them. A poll would also make people more likely to respond, as it’s less effort.
PSA: Always add a “show me the results” choice to keeep the responses fairly noise free.
PornHub should do a poll before the content is watchable 🤔
Stick to Serbian, Slav productions. They’re a goldmine of porn.
