So I noticed that I don't really feel anxiety talking to hot women, but I can't connect with any of them during my conversations.

My conversations with them is more of an inquiry than anything else. I felt like a fly on the wall that had nothing interesting to say. Honestly, nothing makes me feel worse than sitting in a social environment and just standing there....

it reminds me of clubbing where I'm just "one of those guys" who just stands there.

You're in the right place buddy! Most people have more trouble at the first hurdle (fear of approaching), but seems you have trouble at the second hurdle now.

Well, this is what "game" is for. There's no harm in learning some routines or premeditated stories or lines to spew out to begin with. Then you can spin off these to other conversational threads. And over time you will lose the need for any canned lines at all.

Checkout "mulithreading" by Mystery if you haven't already.

Ask the right type of questions when you do ask questions - questions that are open-ended, require the girl to access her feelings or to visualise, that require a qualitative answer, that allows you to gain information about her that you can use for further conversation.

Finding and building commonalities is the oldest trick in the book, and also one of the best. If you find it difficult to do this, you may not be asking the right type of questions, as above. Alternatively, maybe you aren't a very interesting or knowledgeable person yourself? Perhaps worth learning more widely and having wider interests.

Use all the information available. That is, use the situation/environment. You could comment about the bar or her background here. You may notice she has some outlandish jewellery, and could ask if it has a deeper meaning. People like talking about themselves. You could ask her questions about herself that she enjoys answering, such as her interests. If you then make a judgement on how "good" or "bad" her answer is using cat string theory, you can give her something to work towards (your acceptance) and thus she will want to answer and supplicate to you more.

Also use games like thumb wars, lie detecting games, three truth games etc.

Whenever possible, empathise with her position. Remember, empathy not sympathy. This builds comfort.

Take her back to her childhood and ask questions about that. Or if she remembers are certain cartoon. That topic always brings laughs!

At the end of the day there are many interesting things to talk about and derive pleasure from. If you are unable to do this, it may be that you need to widen your perspective; or it maybe that you lack the confidence to try these topics; finally, it maybe (and this is the one I'd most bet on for you) that you haven't started with enough attraction for her to really invest in conversation with you. She might be really interesting and add value to the conversation...if she has a reason to...

Hope this helps buddy x
