How to get over the urges when I look at hot girls ?

Stop looking; find something else to do. Focus on a book, or driving (often it's while I'm driving so it's quite important not to remain distracted) or my phone.

 

The advice is easier said than done: Avoid looking at them and avoid places where you will be tempted to look at them.

There is a certain way to apply this advice properly, but you will have to find out what that certain way is.
