I would personally very much not like that move. If we are fondling, it will get to the point where I'm touching the guy's dick without any sort of prodding on his part, unless he does something to turn me off like forcibly place my hand on his dick.

If you do it without asking, then yes.

Really? Have you explicitly ask for permission every at every step of physical escalation in every relationship you've ever been in?

At some point there's implied consent to continue moving forward. If not, then I fear there are hundreds of millions of sexual assaults every day.
