Most Helpful Guy
I don't know that anything intimidates me any more - what does happen is that girls who obviously like me get spooked if I make it clear I'm interested (and I just can't be bothered to be slow and vague and all of that).
So, if you want to call it 'intimidate' - insecurity intimidated the hell out of me (but only because they can't own up to liking and being liked - without weeks of knowing each other which I just find too taxing/tiring)

It could be anything. Beauty, strong sense of self, not willing to take bullshit, sticking up for yourself, knowing what you deserve, knowing where to draw the line, the list is endless. There's also fear of rejection that you've got to consider as well.1
