Would you be upset if;

You were getting married in two weeks and your brother threw your fiancé his bachelor party and when he got home he had lipstick on his cheek and had a strong smell of lotion. And that when you asked if it was a titty bar or a nude bar they said it was just topless. But I went online because I was curious and it said it was fully nude and you can get private dances or intimate Rendezvous with the girls, then when I asked what happened he said nothing at all. And told me to forget it.  Am I overreacting?
