Master/slave relationships are not necessarily BDSM. I guess I wouldn’t consider a bit of spanking to be crossing over that line. Nor would mere restraints get you there. That all seems pretty mild to me, and it’s about as much as I’d normally want.
Now if a woman really begged to be hurt, and I believed she really meant it, I think I might take that step. However since my wife isn’t into any of it—at least, not so far,—I doubt if I’ll ever get an opportunity. But I can definitely see myself giving in to the desires of a slave who trusted me and who I trusted completely. It would be an incredibly intimate thing, I think, and would open a lot of doors between us. I would imagine it is very freeing in a strange way, to humor a lover’s desires to have you give them pain in a sexually exciting situation.
I don’t know if many people can understand it. It seems so freaky. But it seems to me that it would be very much more intimate than anything I’ve ever done. I’ve never tried it, however, so all of this is in my imagination or in a kind of philosophical investigation. I could be totally off about it. Or expect too much.
