Right ladies heres the answer and I do this all the time so I know it works. Like whats been said above put toilet paper down the toilet before hand and spray a little bit of air freshener if any in the bathroom so the smell is discrete. Also when your going for a NUMBER TWO sometimes we pop out the out the odd fart too so get a bit of tissue in your hand and cover your but region with it and you don't hear a thing!

1. Always go in after he's been, so he wont be going back too quick. 2. Go before a bath or shower 3. Matches and air freshener give the game away. You can hear the spray, and both have their own smell. I put the plug in the sink and run the hot water tap on full, then pour some hand soap into the stream- it all steams up and makes the bathroom smell like the soap! Which is how you'd expect it to smell, only stronger (though I doubt anyone will notice) 4. If it's evening, step 3 works even better with face wash cuz you use more of it and it usually smells more strongly anyway, plus it's your excuse for being in there longer. Wow, I have put WAY too much thought into this :)

I used to hate having to when I first started dating my boyf, I used to take my bag into the loo wenever I had to go, I would tell him I needed to "freshen up". I would then spray a bit of perfume or deodrant around. You could also leave some of your own body spray or toiletries in has bathroom. I also told by boyf I hated his soap and brought him a really fresh lemon smellling hand wash that after it had been used would leave the bathroom smelling fresh!

Strike a match. Nobody will ever know you've been there!

Not a solution but a funnyish story! It has taken me many years of an aching tummy and learning all these tricks to poo discretely! Its only in the last year that I have become confident in my cover ups.... ...Only to find that at my new boyfriends 'shared' house, they have louvre doors on their bathroom! Whats that all about! Devastated! Yet more tummy aches and sleep farting!
