I did 3 sets tonight.

Set 1: I was only able to built rapport, I didn’t know how else to flirt. I learnt name and her career path that’s it. I tried to ask her open ended questions like what she likes about doing a business, like I followed all the tips on how to maintain a conversation. I just couldn’t create a sexual tension or any tension

Set 2: I asked a girl friend of my friend to dance in a club. She said she’s taking a break and then there was no contact later.

Set 3: Started a girl with “hey red really suits you” and then just built rapport with her and some guy interrupted and she just went to her friend.

Any suggestions on what I could have done to flirt and create sexual tension during any one of those sets?
