If you are a guy, then you should now that a boner happens without your opinion having a say ("taste" is not "opinion"), so your whole argument is pretty pointless.
Bullshit. If it was so much about genetics, then we wouldn't see such huge differences between cultural lines (when obesity can go from simple to triple just by crossing a border) and obesity going from nearly absent to 60 %+ of the population in a few decades.The rest of your blather sounds like you feel like you should get a pat on the head for denying yourself an extra piece of fried chicken from time to time. Your assertions, and the fake statistic you threw out there, are completely out of touch with current medical thinking, by the way.

Now, go have that piece of fried chicken instead of trying to virtue signal. While you're at it, try to actually get laid and take a break from Pornhub where getting a boner really is likely to be dependent on little more than looks... because you aren't really interacting with real people.
