I have had to back off of "bi-curious" stuff my wife asked me for.
There was a period where she used a strap-on pretty regularly, which I enjoyed. For me a major part of the enjoyment was letting her "use" me - I don't know what the female response to being penetrated (at all, regardless of the orifice) is like. It is understanding the female response I was trying to expand for myself.
I tend to believe that an orgasm is an orgasm, whatever produces it should be fine, as long as there is no physical harm done (mental, emotional spiritual harm either but hopefully that goes without saying). I think one should be be able to muster some enthusiasm for the activity or wait until one can...
What my wife wanted was for me to accept being taken by a man, and for me to give as well. This would have been done with her directing, so she was (and is, to some degree) interested in the domme side of things but fortunately we completely agree that pain is not good. (NOT JUDGING, JUST STATING OUR PREFERENCES...) She also wanted me to experience swallowing the ejaculate of more than one guy, again with her directing, and also for me to be sucked and manually brought to orgasm by one or more guys.
All with her directing...never as a solo activity.
I am comfortable with the concept but somehow the right partner never presented himself. Before we met she had had a couple of sessions where a domme she knew brought her sub and she was taken by the sub (let's be clear, my wife is NOT into anal receiving) and then was allowed to direct the sub in taking the mistress...sort of as a training and an introduction to the play.
My wife is much more experienced than I am, I have never had sex with multiple partners.
I like the idea of my wife letting me be used as the subject of her instructing a SMALL group of women in the use of her strap on, with each of the women having a turn. This could be expanded into the idea that one of the group would bring her male SO to the next meeting and then he would be the subject so the women could all be properly instructed as to what would be necessary to achieve compliance from a male.
I suppose this is domme sub stuff on the surface of it, but there is for me the idea that the sensitivity to the female point of view would be much increased.
I like to think I will be able to get to a place where this would all work - I do want to perform in the service of my wife...
Chivalry is not dead, in spite of what we observe in the new and in life these days.
I hope this helps anyone reading...
