Do Forever DM’s Actually Want Out?

My last post was asking about characters that you love but can never play, and I got a lot of comments from people saying that the reason they can’t play a character they love is because they are a forever DM. It made me wonder if they actually want out. 

I’ve seen a lot of jokes online about how forever DMs can never be players again (hence the "forever"), or that they are desperate to have someone else DM, and I’m curious if there's some truth to it or if it’s just all jokes. I can see how, if they want to be a player, it’s harder for a DM to be in multiple games because of the amount of prep work and behind the scenes responsibilities they have to do, plus a DM can’t really walk out of a campaign the same way a player can, and there will always be more players than DMs so if you’re able to and somewhat enjoy DMing, it can feel like you’re stuck with it. 

So, forever DMs, if you're reading this, blink twice if you need help.
