Went to a job training program for work and the instructor was just talking about his perversions

The instructor told the trainee that he ASKED a woman at his job for help who had large chest. He described that when she would help him her chest would go in his face. He then got agitated and said that it made him uncomfortable and that he is allowed to tell her to back off. He told his coworkers about this situation and they told him that "she probably didn't know that she was doing that". He said what she did was not right and he was just 19 years old at that time and did not know what to do.

Why would he even ask her for help if he was just going to act like an asshole?

Whenever I report these type of things they just tell me its a: "communication misunderstanding" and that he has ADHD. They told me "he has to teach boys who have autism or intellectual disabilities about these uncomfortable topics". Like these aren't boys they are grown adult men. The compony I work for has to help the disabled community so they can get government funding so there is nothing I can really do.
