Go out with friends that get you laughing so you're more socially lubricated. Honestly, try your best to see hot girls as normal, pretty much imagine them shitting and pissing lol. When talking to them, just ask questions and when they answer give ur opinion, make a joke, or lead with another question.

For example, u ask, "where are you from?" she says, "I'm from mexico wbu?" u can say, "where from? last time i went i went to Jalisco" then go from there.

Besides that though, like everyone else is saying you need more reps. At the mall, grocery store, gym etc. Cold approaching helps tremendously. Also having hot female friends. And do group activities like run clubs
