Apparently you have difficulty reasoning objectively about this issue. Let's agree to disagree and move on with life.
For you it's sexual assault because you imagine him attacking women without any warning while I on the other hand have no reason to believe that he isn't escalating sexually in a normal way, leaving room for women to say no or move a step back to signal a no.
Edit: When I think about it then I must be a sexual predator according to your definition. I cannot remember to have ever explicitly asked a women if I may kiss her.
