I have an interesting perspective on this. I dated a man for 5 years that was a sadist in the bedroom, but I was the one totally in control regarding "normal life". However, I didn't enjoy being in control in the slightest. I actually talked about it with him several times, and we "try" being more 24/7, but I couldn't do it. I think I finally realized that he didn't have the strength of character or personality to pull off being "Domly" outside the bedroom, and that frankly, I found him far too immature to respect enough to submit totally to him. However, recently I have found a Master that I want to have a more 24/7 relationship with, and submitting has been easy and natural. I think it is definitely dependent on the other person- certain people are just not suited to be a Master full-time.
