Title is kind of self-explanatory in a very simple way. I always have this dilemma when exhanging sights with a woman, and approaching or even going for a first date with a tinder girl.

For some cultural context: this is Argentina - we are "kind of" italian. It is not weird for us to give warm welcomes, hughs, and giving kisses to the chicks on strangers - both woman and man. This is accepted, perhaps not in the way to greet every stranger you meet in the street this way - but it does in parties, or hobbys and so on.

Now the dilemma: i always think on which "attitude" should I lean towards when passing by a woman who is checking me out. Should I have this "bad boy" face and kind of aggresive look - those looks that say I wanna grab you by the neck - or have a "happy" face, maybe a little and confident smile and a bright look in my eyes that says "I could easely pretend we've known eachother for years"?

When approaching or having a first date the dilemma repeats:
Be like a golden retriever, happy, eager, warm and welcome. Pretend we've been friends for years and we have a complicity or connection already built - this can provide some solid grounds for breaking the touch barrier from the start - but it may also kill the mistery, or the sexual tension that a "IDGAF" attitude and mistery that a "bad boy vibes" could give - uninterested and a bit superficial perhaps?

Have you tried both? What is your stake on this one? The results would vary consideratively, or it should be the same?

Myself am kind o serious. I couldn't say a have a bad boy face, but it is very often I hear comments on how serious I am - I hate it. But it is what naturally comes from within. Nevertheless I could be much more friendly, but I'm just "scared" of going too far, and breaking the seduction barreer (I neither want to be perceived as a gay friend, if I ever actually was perceived as suchj)
