The culture you have described here is one in which the petty officer would be investigating his boss, if he took it seriously. Was this issue being treated by the culture as something that you shouldn't have complained about and, therefore, minimizing it?
It strikes me that this is an incident worth the committee's attention as a very clear indication of a cultural problem. This was essentially a public call where a senior officer thought it was okay to communicate sexual innuendo with female officers, and he did not understand what he was doing was wrong.
Is that your sense from that experience?
