I have discarded a number of my boxer shorts because of the annoying front slits that expose my thing unexpectedly especially if I'm doing a strenuous work.

I then ask, what is the essence of the openings they put on boxer shorts?

The slit in the front of male under garments is there for a purpose. A man does not have to sit down to urinate like a female and there for does not have to pull down his under pants in order to "go". To make urinating faster and more easily, an opening was built into men's underwear in order for him to quickly and easily remove his organ when the need arises to "go". Unfortunately this can't be done for a woman who has to remove not only her panties, but also her hose and or pants if she is wearing them. Lucky men. before you think I'm intelligent, I copied from quora..what I wanted to type was that imagine going through the stress of u doing your belt if you want to yanch a girl when konji has already entered your body, you just pull down your zip, bring out your bazooka through the slit and start firing....
