I'm curious... did you actually have zero dates when you initiated or asked out?

I see that you tried various tactics for first contact from hints to a direct ask. I'd still say, don't give up. It doesn't mean you're doing anything wrong.

One of the terms I use when describing the mating dance is 'offering.' An offering probably shouldn't be subtle, as so many (especially men) can miss it. Women shouldn't have to be coy. For both genders it shouldn't be a great risk. An offering can be matter of fact, a comment or a smile... that creates an opening, should one decide to take the other up on it.

The thing about offerings, though, it sometimes takes a little time for them to develop. In a world that wants everything right away, we seldom give time for things like this to develop into something more.
