This is light fiction from the days of censorship. The plot is that it is 1940 and two farm boys from Indiana have just turned 20 and have joined the Navy to see the world. They wonder if it is really true that the Atlantic Ocean is even bigger than Lake Erie.
They arrive at New York's Grand Central Station wearing their Navy uniforms. Willing girls wave to them. The girls take them to their place. When the young sailors realize that the girls are planning to have intercourse with them, they climb out the bathroom window and escape. What a close call!
As they continue on their adventures to various ports of call, always there are girls waiting and looking for action. When they travel to other countries such as Iceland in Chapter 13, the boys definitely do have intercourse.
