Munchies:
Oh, no. Not even a little. That will mess both you and your domme up mentally.
While I agree with many of the points you made, I have to disagree with the overall message, as it sounds discouraging. I've seen a lot of posts on Fetlife of people saying how they made a 24/7 BDSM dynamic work for them. It's true that trying to spend every waking moment in an intense sex scene with no breaks or aftercare is a mental health disaster in the making, but that's NOT what most people mean when they talk about lifestyle BDSM. To make this dynamic work, people have to reorient the way they think about BDSM, domination, and even what constitutes a scene. For example, think about nudist couples. In a way, they have a 24/7 dynamic where they've agreed to follow the rule that they should be undressed whenever possible. For someone who only associates nakedness with sex, they might assume that they'd spend all day in bed, but that's not the case. For them, nudity is just a way of life, and the same can be true for BDSM.
Aftercare is still important, but you don't have to treat it like something that happens after the scene is over (since the entire relationship is basically one big scene). Rather, people have to realize that there are many different ways to be dominant. Some are sadistic and cruel, and others are gentle and nurturing while staying in control. In a 24/7 dynamic, the dom should be capable of switching between all of these modes when appropriate, just as they should know when to punish and when to praise. Every aspect of life, whether it's aftercare or vacuuming the carpet, should be filtered through the lens of dominance. Some couples even do a 24/7 roleplay dynamic such as DDLG, where they never turn off their roles, but normal life still happens regardless. Here are some ideas of incorporating BDSM outside of the bedroom:
*It's easy to turn every mealtime into a feeding session, regardless of the amount of food. Even If you're eating out at a restaurant with friends, you will have to be subtle and discreet about it, but the feeder is still providing food or even ordering for him, so it's still a feeding session in their minds.
*She can give him homework, like giving him a large gainer shake that he has to finish while he's at work.
*If they're watching a movie, she can order him to lay across her lap while she hand-feeds him popcorn. To an outside observer, it might even look like normal cute couple stuff, but he still feels like he's under her control and serving her desires.
*Instead of discussing housework responsibilities like a vanilla couple, she can assign him chores, and use treats as a reward for doing a good job.
*She can tell him to do little demeaning things like kiss her feet when she gets home from work, or she can tell him to fetch her a beer, or maybe have a rule to always ask her permission to use the bathroom. These sorts of things can be sprinkled throughout the day so that he's basically always in subspace. Frequent dirty talk also helps.
*With CNC, the idea is that a session can happen at any moment, for any length of time, and without asking permission, just based on the whims of the dom. It doesn't need to be a big scene, it can be like a short micro-session with a single act, like using his belly as a footrest for a few minutes. For these subs, feeling like they're being used and have no control at all is what gets them going.
*This is basically also an FLR, so she will be responsible for all decision making for both of their lives, whether sexual or otherwise. Kind of like the stereotype of a very controlling 1950's household with the genders reversed. Some doms will even assign tasks that are meant for self-improvement, whether that's telling him to research aspects of their fetish, or ordering him to take an online art class for stress relief, or making him participate in her hobbies.
Of course it goes without saying, but you should only do this with someone you know well and completely trust. It's very important to discuss boundaries ahead of time. You could even write down both of your needs and limits in a "contract" format that you both sign. It's not legally binding of course, but it makes things super clear for everyone while playing into the fantasy that the sub is signing their life away. Some subs even feel strongly about not having a safeword, since they trust their dom completely to keep their wellbeing in mind, and feel like they can speak up when they're uncomfortable, and their dom will respect them enough to listen while still having the final say. I wouldn't recommend this for most people, especially if you haven't lived together as a normal couple for a while first. If either of you aren't open to possibly spending the rest of your lives together, this may not be the lifestyle for you. If not, then you don't have to go to these extremes though, the limits of your agreement are completely up to you
