Very, very slowly and carefully. See, you're not just asking for traditional roles or something. Or for some ice cream. You're asking for a relationship rooted in submission and consequences. While I'm sure there are men who are fully interested in that kind of thing...
...most of us just weren't raised to think things like that are okay. Hell, people don't even think you should spank kids anymore. Point is, I don't know that there's any good way or easy way to bring that kind of discussion to the table. Because he's either going to be with it or he's not. I can't see there being too much in the way of convincing. And if he's not with it he might think you are insane and run like hell from you. And I can't say I blame him. But that's because it's not for me.
Which brings it to me. What would I do if I was in your boyfriend's position? I'd roll out. Honestly. And I'd judge you. I would think that there's something wrong with you too. It might not be PC for me to say that but I'd have a problem with my woman asking me to partake in what I kind of deem to be a mild case of domestic abuse, at the least. And I'm sure I couldn't be coaxed into it.
Now, according to the world's most accurate information source, the Internet, domestic discipline is becoming more and more popular among some types of couples. But I feel like that's something you both seek out in a partner. Maybe your boyfriend will be on board. Maybe not, but I don't know any easy way to broach that topic or bring it up.
I think you just bring it to him in a way that explains it clearly, completely, and encapsulates why you'd want to be in that type of relationship and what you think it will add to the relationship. Basically, cover your a$$.
Pun intended.
This is a great post specially because it comes from the husband or boyfriend perspective. It is true most of us, even us women, were raised in this generation with the idea of being equal and zero tolerance for domestic abused.
Asking your significant other about discipline and punishments is not easy.
When I first brought the subject to my husband attention, he was in shock to say the least. After a day or two and realizing how important that lifestyle was for me, he turned around and we been very in tune in DD since then.
The key is to bring it up slowly and wait for his feedback!
Me and my husband are just starting. I've always had my place and my role as his woman, but befor I just got my ass beat down. We researched it together. We agree I get what i deserve he isn't easy on me either but now I realise he does it out of love not to abuse me because his anger. If I step out of my place he corrects my behavior with out me being beat on the floor. This has worked very well in our case.
