Instead of cutting to the chase so quickly why not try something like this...
After some banter why not say: quieres jugar?
Chica: Si, claro
You: Pero me gusta hacerlo todo nena...
That leaves some room for interpretation, but at the very least anal should be assumed.
In my experience this type of exchange has worked best. The idea isn't the specific words as much as the approach.
I understand for those who don't know spanish that this can be a tougher approach. I can see where the intentions of the monger can come across as creepy when being so formal or direct when there is no other conversation to support the moment.
Or perhaps I can start the international gaping signal, that way you can just flash the signal to a chica and she can either shake her head yes or no
Cujo
