Hare Krishna cannot be compared to any sexual cry because the sexual cry is a call for some partner to come satisfy the caller's desire. That means it is sense gratification. When we chant H.K. we are calling to Krishna to please let us serve You. So on the spiritual platform it is the service that is desired, but on the material it is sense gratification that is sought. The rest of the points I think you can cover nicely.
