Hey, I just was on a class trip and had the chance to talk to a few girls I normally don't talk with. So at the beginning I was very cool and smooth but later I had some 1o1 conversations and started to fail:

My voice got lower, automatically avoided eye contact, didn't talk a lot etc, any confidence related thing.. This happened more during conversations with younger girls (14-16, I'm 17) and girls I didn't know well, especially when we got very close face to face. I felt that during the conversation the girls were on a higher place than me and I lost confidence even though I should have had the upper hand, not them. I lost my confidence and feel "needy"..

So what can I do to keep the upper hand and keep my confidence during a conversation with ANY girl? I feel pretty bad right now
