Squatting and My Bag

Hey lately ive noticed that for a few hours after I work legs my balls hurt. And its not the feeling when you get sacked, its like a deep pain. I have a friend who gets the same thing. Does anyone else get this or know why I’m getting this?

My leg day usually consists of 5 - 6 sets of a squat variation. Ham curls, a calf exercise and a ham exercise.
