I dont think it's a question in society anymore. Every single person gets hard every time they think about at least one person in their family and if they got the opportunity would fuck their brains out. They just train themselves not to think about them. I'm firmly on your side - embrace the lust and if they are genetically too close, try not to reproduce

Exactly. People should just let it happen. It's natural to be atttacted. Why force yourself to not do act on it because of backlash from the rest of the repressed who can't admit that they've gotten excited over a family member. As long as it's consensual and you don't reproduce with someone too genetically close like you said, it's perfectly fine.

Agree. All of my early experiences were 'incestuous' and they were a fantastic introduction not just to the pleasure and mechanics, but also to some of the deeper emotion attachments that sex can bring as well. Still happens sometimes and it's still amongst the best just on pure skill of participants. No-one gets forced, live and let live! I like how you think - sent you a friend request btw

Hate to be a stickler for details here, but he didn't say, "don't reproduce", but "try not to reproduce".
If a child is born from an incestuous relationship, there are often good indicators that it won't necessarily be mentally impaired, but rather have a slightly elevated risk of other defects of a purely physical nature.
At least based on everything that I've read on the subject over the years.
