I dated an actress, and she kissed people on the set as part of her JOB.
I hope she enjoyed it, as she had to make it believable and passionate (if the director called for it).
She was an A-list SAG actress, in demand for movies and TV; she had to be comfortable hugging, kissing, being zipped into a body bag (dead hooker role for a police show), and had lines professing eternal love for other men.

It would be wrong for me to be petulant and harmful to her career.
