Ice.Maiden is spot on.
Yes, girls like a sense of humour, but desperation they spot a mile off, and they run a mile, so don't try to be funny if it doesn;t come to you naturally.
What all girls look for in a guy is someone who is genuine, able to be themselves, is nice, listens, converses, takes an interest, and is enjoyable company.
That's added to the 'givens - being clean, apropriately dressed, polite, with clean hair, teeth, nails, and shoes.
Cover the main bases, and you will be fine. Girls are human too - they are not another species!!
