Men and their toilet moments

Now the toilet habits of men and women are completely different, as anyone who has lived with a member of the opposite sex can attest to.
Women are furtive about their toilet habits, and would prefer others to think that they do not have bodily functions of that require toilet visits. Also, despite usually having more clothes to take off, women tend to be in and out in a matter of minutes.
A man will announce his impending toilet visit to all and sundry, will admit to enjoy going to the loo, and spend ages reading in there. Many a man will claim that he reads in the loo because it's the only place where he can get peace and quiet, but I just don't buy it. It makes me wonder whether they are just naturally more constipated that women, or if they actively enjoy sitting in a place that's let face it, is not usually a prime spot to hang out in. One ex told me that men actually enjoy their number twos ( see being a woman I can't even bring myself to say "having a shit" ) because it stimulates their prostate glands. Saying that, he was weird so I don't know whether to lend this any credence.
I have a Facebook friend who is married to a real life friend of mine, who actually does status updates on his bowel habits, and his friends comment on them. Can you imagine a woman doing this ?
Which brings me to farting. Women are usually deeply embarrassed to  admit that they actually do, but men will brag about it, have competitions with their mates and be proud of "clearing a room". Evolutionary Psychologists claim that men farting is a way of marking their territory - but then as evolutionary theories are non-falsifiable, I am not so sure. If this is the case, why do they set fire to them ? And believe me they do - it was another ex's party trick to do this !
