2. You say "do not do that," he blushes, apologizes, the date continues, and you kiss him on your doorstep. He puts his hands on your waist drawing you closer and you kiss him more passionately. He moves his hands up to the base of your breasts. Sexual assault?

3. "Don't do that." He blushes, apologizes, and you chat for a bit. You invite him in. You begin to kiss him again, kissing his neck, and you can feel that he is ready to take this to the next level. You move your hand down to hold him. Sexual assault?
