As a bi guy, I find realistic toys a major
turn on. Even so, it was a little awkward at first, both for my wife and for me.
My wife wasn't sure what it meant, or was supposed to mean, for her to strap on a penis. Once she understood that for me it was pleasurable and fun, she got into it and now loves it almost as much as I do.
As for me, I was worried that she might disapprove of my desires. Fortunately, she was both amused and somewhat aroused to see me 'suck a cock' and later to see me bend over to be pegged by her.
I'd say our first discussion about strap-on play was the most awkward part. After that, it was more exciting than anything else.
