I personally am OK with bachelor parties. I know that I am a lot more laid back than most people though.
Granted, I don't want him going every night, I'm ok if he does for his bachelor party. We live 8 hrs. away from his family and most of his friends that he grew up with. I think lots of times guys just don't know what else to plan! It's kind of what is expected!
I say if that's what he wants to do then go for it. The reality is nothing will happen, other than some girl rubbing her boobies in his face. He can't touch them! Depending on local regulations, he might not even be able to drink at the strip club!
I'm looking at it as a don't ask, don't tell situation. I turst that he will come home to me and he will marry me, no matter what happens during a 6 hour time frame. We've been together for 6 years! I feel the same way about my bachelorette, if my friends hire a male stripper (gross!) I'm not going to brag to FI. It will just be something that happened on girls night!
I really don't think you have anything to worry about!
