Yes Greg and Charley, I think that's probably it. I have thought that as well as having the word "virginity" in it this song is also about male conquest. Funny though, the compiler of the rugby songbook didn't seem to be short of songs that were much more explicit.
Charley spare a thought for someone whose ancestors gave me the family name - "Semmens". It's hard to explain, with a straight face, that I come from "sea men".

I suppose the reason for my posting this question is a carryover from childhood. From the time other kids made you say a word with a double meaning so that they could laugh at you. And you never knew how to avoid it, or what you'd said.
You learn how to avoid the problem but it still puzzles you.
