I've never really had a problem asking out a guy. I mean, I'm really shy when it's someone I really really really like, and it'll be the hardest thing in the world to do... When I met Mike, because I liked him so much, I wanted him to make the first move, because I wanted to know that he felt the same way. So, sometimes, it really all depends of the circumstances, and the person's shyness.
I was the one who asked if he wanted to go out for a drink, just as friends. On our "friend date" we both felt high chemistry going on, and he ended up asking me to go on an official date that weekend.
Now we're about 1 1/2 years happy in love, waiting for our first child, and want to get married in the near future lol. And I was the one who asked him first :P
