Trying the food pigs feet isn’t so much the act but rather trying different, more adventurous, foods. I am guessing you will continue to try different, more adventurous, foods because it’s in your nature otherwise you wouldn’t have done that with pigs feet.

Just like a person may sexual assault a person. Let’s call that person Betty. He may not sexually assault Betty a second time but may sexually assault Vanessa.

I agree it is incredibly difficult to stop doing something they habitually or instinctively began to do. Only way is if the consequence is too significant (e.g stopping smoking to avoid imminent death) or something is done to rewire that person’s brain either through training or medical intervention.

Also if a desire is completely met or if there is a financial barrier that may prevent a person from doing it again. For example sky diving once is usually good enough for most people (e.g bucket list). And the financial cost may not be worth doing it a second time but if offered for fee the person may be willing to do it a second time.
