Very interesting topic. And you are right, prior conventions no longer come into play. I think men are going to just have to work harder to KNOW the woman they are dating before "moving to the next base." Most times, if the girl wants to ramp things up, you'll be able to tell. And, rather than feeling like you must stop, back up against the wall, and ask a formal question, I'm guessing a real look into her eyes, coupled with a soft "Ok?" will usually suffice.
