i laboured under the rather terrifying belief that in order to make a baby my seed would have to be put into my wife. why so terrible? unfortunately i thought surgery would be involved in removing one of my two 'seeds' (i now understand the surgery to be known as castration and largely unrelated to dedicated couples reproducing). as you can imagine, it took me a long time to realise that one day i'd actually love to father children: consequently, i blame the parents!
