If you think about it, intercourse itself even when done with care and love in the traditional missionary position is a somewhat violent act. For most males to ejaculate, they must thrust with some force. It even looks violent.

On the receiving end, no matter how good it feels, how much love there is, the woman is still being penetrated, her body entered by
a foreign object.

The term intercourse implies an interchange, an equal exchange, but that is not truly what happens. The female gives nothing, penetrates nothing in traditional sex. She receives. She is penetrated. She is impregnated.
