If she was willing then it wasn’t “harassment.”
I think that philosophically (not legally, before someone has a cow ...), a person can be sexually harassed, and it is still harassment even if the person puts up with it. One of the points of harassment, after all, is to wear down the target so that he or she will “willingly” “consent” to something that’s not wanted.
In a different context, some of my teenagers are excellent at this. They hassle me until I “willingly” do what they want, even though I don’t want to and don’t think it’s the right idea. It leaves me feeling angry both with them and with myself.
