You need to have got 8 people to offer to see you later before getting your girly bits fixed. Most of these can happen at any point before the 'beautification', but as I'm not a very nice person, if you tell someone about Bach's Orchestral Suite No. 3 in D major, you're 'bonked' unless you have a saved game before you were such a smartypants.

Look carefully at the boxes surrounding the sets of numbers you found for the pornia key combination, that should give you an idea of the order of some of the numbers.
The locked door inside the room at Blarney Castle with the dirty numbers is purely decoration (same as the safe in Ms Chompalot's room (just a little hint if you opened the first cupboard in his kitchen knowing you need French Mayonnaise ...but also gets him to ask you back to his room later, as does talking to him with any of your clothes missing. Don't forget that he's just a randy Frenchman)

You don't need anymore blood after you've chucked the fake stuff, you just need to get into Pornia and find Molly's place.
Getting into the Penal Colony is the prize for solving part two of the game.
PS - Simon, think 'up yours' and machete
