Gents (or bi-females/lesbians), how do you act when meeting a stunningly beautiful woman?

Do you try to be a charmer (all smooth and whatnot)? Or, do you act like a bit of goofball (all nervous, maybe, trying to be funny), or do you have a deer in the headlights look with a perpetual smile (which can be a little off-putting, ha)?

I’m a gay girl, and just recently I went into my insurance office and met an extremely attractive older woman (she looked like she was in her early 40’s). She had a beautiful smile and was absolutely stunning. When talking to her, I had a stupid smile on my face and felt like a dork. We chatted for a good while (she was very talkative) and a few times I stumbled over my words, all nervous-like bah. She had a big smile at the end of our convo and I’m wondering if she could sense something. God, I hate when that happens..
