I think it is about knowing your partner. My husband wouldn't cheat....in this situation. Nor has he ever allowed alcohol to lead him into making a bad decision. Doesn't mean he wouldn't, but he hasn't. The last bachelor party he was at the bunch of them (5 guys) bar hopped and ended up in a hotel room around 2am with the highlight being an order from McDonalds. I'm the partier of the two of us when you look at our history. I'm the more impulsive one and a hot mess when I drink. I'm not naive enough to think he would never cheat because I know it happens. He would be much more likely to have an affair with a female friend or co-worker or even a woman he met on that Ashley Madison site than a stripper at a bachelor party. It doesn't do my any good to waste time trying to snoop around and prevent him stepping out. If I noticed a change in him, then I would investigate that and do what I need to do for myself if I found anything out. I think you can trust someone but also be aware that they may disappoint you. I wouldn't want to waste energy trying to hold onto someone who doesn't want to be with me. That's energy taken away from myself, my children, my own activities. I have enough going on without worrying about the what-ifs. I imagine many women may feel similarily.
You women really believe you could trust your dh at a bachelor party/sleepover with strippers? Lol! Its the women who think it will never happen that are shocked beyond belief when they find out their husbands have cheated. A man is only as faithful as his options. Getting drunk at a bachelor party sleepover with naked women, who use their sexuality to make money, and you trust your dh. Ha! I wouldn't need to allow my husband to go, he knows if he does, no need to come home. Alcohol and temptation can make the most loyal dh slip.
Sure, what is he gonna do? Sleep with them? No, he is smart enough to know better than to touch, (I mean imagine the child suport and all that fun stuff if he cheated, cause this lady would be gone) but he can look and enjoy all he wants. He went to a strip club for his bachelor party and it was no big deal. =] He's a big boy, and I trust him.
