Most Helpful Girl
I think playing a little hard to get is a turn on, but only in a small does in the beginning. Playing hard to get would make her want to be around you and figure out the mystery of why you are untouchable. However, like I said, it should be in ONE small does (like maybe two or three separate times) because anymore than that and I would just start ignoring you. After you've done your part, it's your turn to make the chase and woo her so that she'll consider you to be a good date and potential bf-> then you ask her out.
But, at the same time, being straightforward is just as good. Just make sure she likes you back. Being straightforward cuts through all the "maybes" and doesn't exactly waste any more time.0
