Nutty,
I generally don't want to just sleep with any woman. I've a great deal of respect and admiration for all women, and it shows in the way I talk to them, treat them, and am simply "me" around them. Women can sense "realness," and are attracted to it.
A man will sleep with a woman on the first date regardless if he likes her or not simply because his instincts tell him to. A woman will only sleep with a man when he has earned her trust. By this I mean, she trusts that he will be there for her regardless. This is because when a woman sleeps with a man, it could potentially be a life changing event for her. This could be 6 months of dating, or even the first date. It's up to what she feels about him as an honest, good man.
I have plenty of lady friends, and I am fortunate to be surrounded by good women. I suppose this is because I am honest, and good to them. Generally I never show up at an airport without someone waiting for me. Why? they know that they aren't the only one, but they accept that. It's about adults, honesty, and friendship (albeit with benefits).
I don't think that group of people on that boat are fake. Maybe a couple, but I would realize which ones in a hurry. I'm around people every day, and most I've learned are genuinely good.
