DON'T TAKE ADVICE ABOUT WOMEN FROM WOMEN
Well I would never take particular advice from women but I have a few pretty decent looking girls who are active in the dating world who I am just friends with (and I am happy with that arrangement mind you, even though I've had some fun with one of them in the past) who are open about sex and I use them to interpret girl code for me.
I ask them specific questions and advice though. Like if a girl says something to me what could it mean or I ask them how girls would approach a certain issue so I can be ready for what may be lying ahead. Since they are active girls themselves they know all the tricks and moves that girls use and are happy to tell me. Their advice has checked out on numerous occasions so I trust them.
I would never ask a question though about "what do girls like?" and stuff like that cause you will just get stock answers. But for specific things like "as a girl could you tell me which shirt looks better on me" or "a girl made up this excuse, is this legit?" they are pretty reliable if you are good friends and open to eachother on that level.
