Is it normal to all of a sudden run out of things to say

Yes it's normal. Just relax and ask him questions about what he likes and he'll ask you things about yourself. You'll get to know each other a little more while actually having something to talk about. If you did that or it doesn't work, talk about random things you saw in your day, tell him stories about yourself. I think it's pretty fun and interesting to know stories about people.

I prefer shy women to answer your second question.

Yup, and it sucks, because girls want us guys to get their interest and then keep it. Sometimes you just hit a lull, and there's not much you can do. Try and keep track of things that they've said earlier; think of it as cross-examining in a legal case - you're coming back to something they said earlier from a different angle. They'll know you're listening, and maybe you can keep that poor fragile conversation going long enough to touch your lips to theirs.

Definitely some good advice in here, I agree with momonator just ask him questions about what he likes and tell him stories. It's what I do whenever I feel a silence is starting to happen and it always works. And shy but outgoing girls are the best :)

Just keep asking him general questions about himself, he'll think you're really interested in him and you won't have to talk too much. Men love to talk about themselves (they're not usually great listeners).

Story of my life, all except the boy thing, for me its more with people in general. Idk what people look for these days, they say be yourself but that really doesnt do me any justice lol. As for the guys' preference in girls, it all depends on him. Well, you claim to be comfortable and outgoing, if you are just that and he accepts then all will fall into place. Dont go against nature! It always comes back somehow.

Boys like both! Shy and outgoing.. That's like saying she's cute and daring.
