As a young man I needed an outlet. Went hunting, fishing, played softball, lifted weights, chased women, rode motorcycles ....didn’t need a shrink or drugs (cept beer) as long as I kept busy. Lots of testosterone to burn off. Nothing bizarre about that.
Nope, nothing. Nothing odd about contests of strength, either, imho.
However, you didn't include "loving to hit people" on your list of normal youthful male activities.
