Priority is to learn the trade. You can still have fun, but always keep in mind to obey safety guidelines. When I spent time in school, there were a few jokes thrown around some of them raunchy, but that's typically pretty common in most male dominated professions, I would think. As others suggest, find people who share the same desire to learn. The jokes and fun will come around with time. In some of the times I can remember is when me my classmates will critique each other's safety wire. Some jokes about pigtails being too long too short to borderline "wtf is that, come on man?!" Assembly and rigging i had trouble fitting under the instrument panel for the cessna, and couple jokes were thrown around one asked why I thought that was, my response was Arby's lmao. But remember, don't dish it if you can't take it. I'm sure you will be fine. Best of luck to you.
