I keep coming back to this one. If you oil up your hard young cock. It will slip a little bit more through the ring. Eventually getting you balls deep.
That's what I've always done, any time I see something I always wonder what it will feel like and can never resist the urge to try! Doesn't matter what it is!
Don't be jealous. Just let your imagination run wild. If you see an object and wonder. What would it feel like to fuck that? Then just try it. Only way to know for sure.
Another example of looking at an object and thinking. Will my dick fit in that? What would it be like to stick my dick in that? Well now you know. It feels great
