If you are currently in a vanilla relationship, your partner will likely refuse to wear diapers if asked outright. Most men will instantly recognize the reduction in social and sexual status that diapers would bring. If he has a particularly large ego, he might even be offended at the request.

Instead of starting off with diapers, start off with a conversion where you explain to him that want to be in control during sex and that - if he agrees not to masturbate or look at pornography - you promise to give him 3 sexual experiences per week in the manner of your choosing. Given that men are heavily motivated by sex, he will likely be excited by this idea and happily go along with this. However, if he refuses this step, then it is highly unlikely you will ever be the dominant partner in your relationship, let alone be able to introduce diapers. He will probably attempt to control the relationship, and this is something you'll have to consider as you move forward with him.

Assuming you've gotten him to agree to your deal - 3 sexual experiences per week in exchange for control - we'll want to get a little sneaky. We're actually going to be using those 3 sexual experiences each week to condition him to ejaculate too early during sex. By turning him into a "premature ejaculator", you will be able to slowly chip away at his ego. Once his premature ejaculation problem is sufficiently severe, you can start to approach the topic of diapers as a potential relationship saver. Note that his premature ejaculation problem is reversible through frequent edging. I would recommend explaining this to him once his stamina starts to decrease significantly. While we could break him down with this, our true goal here is to give him experience as the submissive partner so coming clean and getting consent to progress further is the ethical coarse of action.

While there exists a large amount of information on the topic of curing premature ejaculation, there aren't many guides on how to cause it (though they do exist). According to medical literature, there are several physical and psychological causes of premature ejaculation, but there are two we can actually cause directly: 1.) a penis that is extra sensitive to stimulation, and 2.) performance anxiety. With that in mind, each sexual experience should make his penis more sensitive, and a suitable consequence needs to occur if he ejaculates "too soon" in order to foster performance anxiety.

It may sound strange, but in order to make his penis more sensitive, he actually needs to feel less stimulation during sex. Over time, his penis will respond by becoming more sensitive. For this reason, always put a well fitting extra thick condom on him during sex, regardless of what type of sexual experience you are having. If he protests the use of condoms, tell him it's for easy cleanup and demand they be used -- after all, you both agreed that you are in charge in the bedroom! As his premature ejaculation problem worsens, we'll introduce lidocaine (a topical numbing agent) and even more condoms.

How long he should last is obviously subjective, but your own orgasm is probably the best timer. However, that does not have to be the case, and it can be something arbitrary, like 10 minutes. Should he orgasm too soon, immediately stop touching him the moment it's clear his orgasm will happen and end the session. In addition, chip away at his ego by expressing extreme disappointment and ridiculing his inability to hold back his orgasm. Of course, if he does not orgasm too soon, then make sure it's as pleasurable as possible and show your appreciation for his ability to delay his orgasm. One caveat - if he cannot cum in 20 minutes, then he doesn't get to cum that day. Stimulating his penis for more than 20 minutes may adversely affect what we're trying to do to his sensitivity.

Your goal during sex is to make him cum too soon, which means never letting up when he gets close to orgasm. In fact, bear down if he starts to pull away, go faster if he's getting too close, do anything that pushes his buttons. Try to avoid edging him by making him cum as soon as he gets close. Make it happen too quickly, then ruin his orgasm and mock him.

If he cums prematurely for one full week then add a generous amount of lidocaine cream to his penis 15 minutes before putting on his condom (I recommend Aspercreme with Lidocaine Maximum Strength Pain Relief Cream). If you've already added lidocaine and he still cums prematurely for a full week, then add a second condom. Once he's cumming too soon with both lidocaine and two condoms, he will start to become increasingly desperate. In order to "be supportive" of your partners performance issues, start decreasing the bar for "too soon" so that he has a small chance of delaying his orgasm just enough. If he succeeds and meets your newly lowered bar, give him a full orgasm and patronize him with false praise but tell him that you mean it sincerely.

At some point, your partner will be reliably having orgasms in under two minutes. Some may even experience orgasms during the application of lidocaine, or when you're putting on their condom. This is what I call the "peak desperation phase", and it is where your partner is the most vulnerable. Here, we can take advantage of that vulnerability to confirm his fears - that his current lack of stamina makes him completely useless in bed. Fortunately for him, there is a relationship dynamic that you've been wanting to try where you move control out of the bedroom and into every day life. And as long as he wears his diapers, you'll overlook his complete lack of stamina in bed.

Recap:

Stage 1:

- Any kind of sex 3x per week, always with a condom (even for hand jobs or oral).

- Cum too soon 3 times in a row, go to stage 2.

Stage 2:

- Any kind of sex 3x per week, with a condom and lidocaine.

- Cum too soon 3 times in a row, go to stage 3.

Stage 3:

- Any kind of sex 3x per week, with two condoms and lidocaine.

- Cum too soon 3 times in a row, lower the bar for "too soon".

- Cum in less than 2 minutes, 3 times in a row, have "the talk" about saving the relationship from his sexual inability through the use of diapers.
