Hmm. This is good practice for you when you finally get in the navy. You will be an extreme minority and half the guys will try to get in your pants, and the other half will act completely innapropriate to you. Get used to it now while you can at your leisure and you will be far ahead of the game....
That said, these jokes are awfully mild to what you are going to see in the nav.
Now, now, Charlie. The Navy consists entirely of outstanding professional sailors who would never dream of doing the sort of thing you suggest. Why, it's completely contrary to the core values of Honor, Courage, and Commitment, and nobody would ever dream of stooping to that base, foul level like a Marine or something.
Why, I look back on my service days with a certain amount of pride, knowing that there was absolutely no sexual harassment or discrimination aboard the US Navy vessels upon which I served. Because the sailors I worked with in the fleet are all professionals, mission-oriented, and dedicated to life, liberty, and the pursuit of all those who oppose it.
