I don't like putting my mouth on a can to drink soda. When I have soda in a can, I prefer to use a straw. However, if you just put a straw in the hole, it will move about and it's hard to manage when you are holding the drink in one hand and doing something else with the other hand.
A long time ago, I found a way to hold the straw in the can and it does not move. Just for curiosity, I looked on line and found that I have been doing it wrong. There is another way to put the straw in the can.
I like my way better, but I will let you choose which way you like best if you are not already doing this.
