FH bachelor party

Alright, so my FH had his bachelor party this past weekend and I obviously wasn’t there to know what went on but when he came home his boxers were completely ripped and when I questioned what happened he said a stripper tried to pull them off. He says absolutely nothing happened and I trust him but at the same time I feel betrayed. I just don’t understand how ones boxers can get ripped the way they were without said stripper putting her hands down his pants. Am I wrong to be upset or should I just let it go?
