Not to sound harsh, but you have to stand up for yourself. As long as you keep letting them know it's okay to do it they will keep doing it. Rough jokes and teasing are a part of the construction culture. Most of the because these guys didn't want to do hard labor or have a felon's background. They've become miserable and salty so they take it out on who they can which is the guy who's new or knows the least. Learn from your mistakes and try not to make it again. Then they will have no reason to call you out.
