**Yes, I’m back it with this series, so if you have questions for ya girl, feel free to shoot me an email: firstname.lastname@example.org and asked away. Also you can be ANON, if you want!!**
My advice would be to let her pick the girl, not you. Or you both pick the girl together. Trust me, some females have a problem when the guy picks the other female. Because they are wondering who is she? How did they meet? How did they get on the type of good terms for him to be even asking her to join in.
Since she asked you to pick the female, my suggestion would be to just take her out for drinks (not to get her drunk, but to help her relax) and somewhere that has a dance floor. Get her up and dancing, and playfully flirt with other females (not just you, her too). If the other women is flirting with you both throw subtle hints, like my girl thinks your cute (we wanna take you home) things like that. But also get them two to talk. Being that your girl is there, she has to send signals to the other female like its cool, you know what I mean. Then if the female bites the bait, usually she will seek approve and touch your and your girl. Then you can simply ask, and see what she says. It’s all about low pressure, the right signals and body language. You’d be surprised.
Or you can simply ask someone you know that has done it before, to help you and your girl experience that.
Anyone else care to share their thoughts?
Thanks for asking, and keep the questions coming!! :)
