Because much to my surprise I find it hot, and so does hubby. I guess guys grow up with a hang up about their cock sizes like we do about breasts (and the rest of our bodies!). And the fact that there’s nothing you can do about it make it somehow hot to tease about.
You’ll probably have seen I don’t go in for the full on humiliation, it often goes too far on captions and things I read, but while exploring chastity, much to my amazement, I’ve gone from not caring about cock size at all, to big cocks being a big turn on.
Part of this is the reality that we started playing with him wearing a strap on while caged (https://keephimcaged.tumblr.com/post/142420932962/why-i-love-our-strap-on) and when we used our beloved King Cock dildo in it… I actually orgasmed from penetration alone for the first time. What’s not to love about that?
I’d not do the penis size teasing if it didn’t turn both of us on. A big part of it is that hubby doesn’t have real issues about his cock size. He has a nice cock, so I’m not tapping into some huge inadequacy when I tease him about it. If that were the case then I’d not do it, and find something else I’m sure.
But for us, and I think a lot of readers, the posts like the ones earlier, where his cock size is an excuse not to let him cum or to cage him up… well it’s a big turn on for us both.
