I'm confused. Are you asking for advice on how to talk to women?
You talk to them the way you would expect to be talked to if a woman approached you someday. Just TALK to her and see if you pick up any good vibes.
If you're a chilled out person then try and have a chilled out conversation with her. Talk about something stupid, it's really up to you and what your interests are and the topics of conversation you find easy to discuss. The reason people get friend-zoned is because they're too slow to show the girl that they like her.
If you want a quick f*ck then I can't help you. If you're looking for a woman then don't f*ck around cause the women that respect themselves and will treat you the way you want to be treated can very easily differentiate fake vs real men.
Keywords: men. fake. vagina.
I just realised that you may also be asking on how to talk to females in general, like in a friendly context. If you have issues with that, then I recommend you work on your confidence. Do what makes you happy and then try talking to women. Just give everyone a smile and you'll get smiles back. Some will give you dirty looks, and those are either taken/people you wanna stay the hell away from lol.
