Do heterosexual men really normally have lots of opportunities to compare erections?
I don't know about Men, but Boys do. I know I did in the changeroom in the 5th grade with my friend. We compared our hardons and the rest of the boys in the class were like "huge", "look at the curve"
....bwahahhah. Those were good old times. I still see this friend around from time to time, he has a family (2 kids). It's no big deal.
