It is normal to want to poo/pee when you go on the computer?

When I was a kid, I always used to get excited about using a computer. Always. And whenever I get excited, I get a bit...flatulent..and desperately need to pee or poo and always had to go whenever I got on. Now, I don't get excited at all as using a computer is just normal. But I think that all these years of excitement eventually hardwired into my system always make me wanna meet the throne whenever I turn on the magic box!
