I get with unfamiliar girls at clubs with relative ease, but I’ve never been able to do anything with a girl I already know, no matter how much she likes me. One girl would even always talk about how amazing she thought I was to her friends and clearly thought I was way out of her league, but still every time she’d engage with me more sexually she’d suddenly withdraw as if it’s something she can’t do.

The reason it’s annoying me now is it’s the same sort of scenario again but with a girl who unlike the last one I find extremely attractive. She’s really flirty with me in her over-the-top Italian way, but there just seems to be some sort of invisible barrier there. Maybe do I put it there without knowing? I'll be fucked if I know.

So I just can’t comprehend that I don’t have much trouble sussing a random girl who has no reason to like me, or think anything of me, but with girls who actually do know me and like me I just can’t do anything?

Any suggestions about how to get over this weird obstacle?
