Is that something other men want to do? Even my dog had no interest in it and he was easily flexible enough.
You shouldn’t get your dog to suck your dick, no matter how flexible the dog is.
I’d imagine that gay men, if any, might be interested. But no I think most guys don’t want to taste their own dick.
I wonder if that’s actually the case. I imagine that if I had the body of a (hot) woman then I would be turned on by my own body. However, I haven’t heard of gay people getting off while looking in the mirror…
