first one will get you blown out, or shit tested till you fail (see: -interupt- you are doing a survey in a club, stop hitting on me and fuck off), 2nd they don't relate the conversation will seem scripted and awkward. You need something with lots of conversational hooks (little things they can comment and have opinions on).
"hey guys, I need your advice on something. I have got a friend coming in a minute, we are like best buddies and have known each other for years and I know he is going to ask me if he should move in with his girlfriend. The thing is he is my age and has only known her for a few months. It seems like a bad idea but I think he will think I am an asshole if I tell him not to do it, what do you think I should do?"
this is a slightly lame version of one I use when out with MM guys but it gives you an idea of what to go for. As they can talk about him moving in, him being too young, past experiences of living with guys, it being too soon.
And so conversation will flow naturally plus the he is coming in a bit adds urgency and like you really need their help not just asking them if they will sleep with you.
I think Gambler has something similar in his book probably worth buying as it is only 1p at the top of the page
