Cock ring?? 
I know what you mean. Well you been together for 3 years (if not mistaken), but you don't live together (I remember you posted recently you guys didn't). She don't wanna live together first? Would you get married again? What about more kids?
Damn, lot O' questions

For all intents and purposes we live together, but technically, no...we spend every day at one of our homes, and it's very rare we don't sleep together. It makes no sense economically and we are planning on changing that after the winter.
We have no plans to have kids, but if it happened we would be ecstatic to have a child of our own, even if it would be tough. I'm not always safe when we have sex, and we are both aware of the possibility of a little Groink or Groinkette popping out.
If we got married we would do it on an island somewhere...invite our real true friends and family, whoever can make it shows up. Nice big party, and we are already on our Honeymoon. I think BigBobs did this, and that's what we have in mind.
And yeah, i would marry her no problem
