Try starting off with little not sex related things and build from there.
That's what worked for me as a Dom. I told him he needed to change his shirt before we went out.
Look around online, there is a lot of info out there.
If he's open to it, you could refer him to some BDSM information. There's an easy to find "nice guy's guide to kink." (google it)
That helped my boyfriend a lot.
But when it comes down to it, it may not be his thing. If it's something you need in your relationship it may not work out. It can't hurt (too much - maybe) to try showing him what and why you enjoy what you do, but it may not end in him being your ideal master.
Best of luck!
Many people have trouble adapting to such an idea. One thing I would recommend is lots of research, learning, and discussion. Effective relationships of this sort are more nuanced and complicated than many people realize I think. As far as roughness is concerned, one practice I like to use is graduated roughness. Start out gently and let it grow and grow. Once you get to just the right level, let it be known. One fear is going to far and causing harm, but I think the graduated roughness technique is pretty effective at preventing that.
I'm with your boyfriend on this one, maybe you should find someone who shares the same interest as you? And personally, I have NOT EVER had this issue with my boyfriend… we respect each other.
Well, whatever floats your boat honey. If you like BSDM, you go forth and do it!
You didn't say whether you are dominant or submissive. If you are dominant, then I will let you water my oak.
Time to break up... and move on.
