I think I may have hit on a way to get more sympathy for the imprisoned creatures at SeaWorld. The way to think of the animals is like your genitals. When you're single, their free to be in their natural state, you provide protection for them and clean them regularly yourself.
SeaWorld is what happens when you get married. You now have a consistent set of genitals to satisfy for the rest of time or until what's attached to those sex organs is no longer desirable to you. The difference is that you have to satisfy hundreds of other naughty bits on a daily basis and they better orgasm every time or you will not enjoy the consequences.
On top of that, the regular cleaning your reproductive pieces got is done by someone else because did I mention you now have Alligator Arms? Yes, your arms are too small and uncomfortable to be able to take care of yourself. You need to be isolated from touching other genitals as well. They also do your laundry and pick out your body wash. They may not use the same detergents you were used to when you were free to use what was comfortable for you to clean yourself with.
Oh, those consequences for under performance? I won't go as far the as the torture/euthanasia route in this example but what about freedom? It sounds nice at first but your arms aren't going to grow back to normal size so ife for you will not be simple. Also, you didn't cook or clean yourself for a few years and now, darn it, you forgot how to do it properly.
I'll stop there and let your imagination do the rest.
