That was a very, very bad opener. You essentially skipped mid game entirely and straight up said "I want to know if I can fuck you."

Try something simpler like "my friends girlfriend kissed another woman do you consider that cheating?" Although you generally use it on a set. From personal experience it's a good opener but gets too deep too fast and I, personally, find it hard to move away from that topic.

If it's just one woman open simple, take notice of what she's wearing or doing or if she's happy or sad and just comment on it. If she's buried in her phone just say something like "Are you lost too?" and then be fun and say you two can go look for friends together.

If she's not smiling this opener ALWAYS works but you need to deliver it well(Smile and then grin after): "You should smile more often." It's that simple. You can press for her to show you a smile after that too but in a playful, non-threatening way. After that you can talk about anything like where she's from, what she does and get her name or what she's doing there which prompts her to ask you questions and generally gets the conversation going. Before you know it you're five to ten minutes in and you have rapport. You can just be fun and probe her for more personal information like her interests and favourite movie and stuff like that. If you deliver it with confidence and don't lean in or come across as wanting to fuck her there and then you'll eventually carry the conversation naturally and be able to bounce with women.

Right now focus on your openers more and try a mix of different things to say, gauging what works and what doesn't. Once you nail openers and you know they're getting the reaction you want(Read: You're comfortable with them) then focus on your mid-game.

It's not necessarily your opener. I have heard of guys opening successfully during the day with the line. "Are you single?"

It conveys a high level of confidence, and it can put the girl on the defensive. The problem you may have ran into is that her friend was there, which put even more pressure on her. But she unloaded it all on you when she asked if you were out picking up girls.

When she asked why you were picking up her, you should have given her a genuine compliment, something specific. There's no point in hiding your interest at this point, she already knows you are into her. During the day, there isn't much point in beating around the bush too much. If you have to, I'd even suggest a canned compliment so you have a legitimate reason to talk to her. Throw in a little banter with her- and ask how her day is going.

Nothing to be overly concerned about- just ask normal questions, but make sure your interest is clear.
