Shared a few communal showers with my father in law when on holiday, both tried very hard to get a good look at each other’s penis without being obvious, he looked about the same size as me but his glans looked a lot bigger. He only made one comment once after my wife had tried shaving me for the first time, I had gotten used to being smooth and never gave it a thought until just before we entered the changing room it was too late to do anything so I just carried on regardless and hoped he wouldn’t notice. No chance, he asked if I was ill so I had to explain it was all his daughter’s handiwork and we had tried it for fun. Luckily I didn’t have to explain she preferred it for oral sex.
