Why do men take like an hour to poop

So my SO poops every morning. I have to wait like an hour to pee because he sits and poops for that long, my ex did this too. 
When I poop it takes like 5 minutes, I poop and I'm done. He takes forever and stinks up the bathroom so bad like do you just hold all your poop in until the morning? Why do men do this? Do men just take massive dumps like WHY DOES IT TAKE THEM SO LONG TO POOP AND WHY DOES IT SMELL LIKE 1000 TIMES WORSE THAN ME WHEN I POOP LOL. 
Hell sit in there and watch videos and sometimes he'll try to have a conversation with me whilst pooping and I'm like can you just focas on your poop please? FOCAS. I NEED TO PEE.
