I met some real women off of AM, and slept with one of them. If you want any success, you'll need to be a paying member. Know that the gender population on the site is HEAVILY skewed towards males. It's a real sausage fest, but if you can distinguish yourself with a nice profile and articulate messages, you can find a match. A couple points, though.
1) The quality of the women is nowhere near what you find from providers. As a 30-something average looking male, I was competing against tons of other guys for the very few 6's and 7's on the site. All of them are older, nearly all of them are on the heavy side. There's a reason these women's husbands aren't giving it to them any more.
2) It's nearly as expensive as the hobby. In addition to hotel rooms, you need to wine and dine the women, and buy AM credits.
3) It's a relationship. If that's what you're in to, then great, but I have enough female drama at home, I don't need another woman needing my attention and getting all huffy because I didn't answer her email right away.
4) If you want to use AM, here's a tip -- go to your settings, and turn off "Marketing Preferences." This is where AM sends you fake messages, causing you to spend money responding to them, all in the name of "marketing." The site as a whole isn't a scam, but that part is.
Good luck!
