There are 2 ways to understand how to get a guy to like you on your first date. The first way is to Ask Your Girlfriends, consult with your mother or aunt, or maybe read Cosmopolitan every week. The common thing about these sources - They all come from Women.
We women spend an amazing amount of time dissecting and analyzing every little aspect of relationships, men and life in general.
That, unfortunately, doesn't mean that we understand men better (than men).
The second way to know how to get a guy to want you is to Finally listen to what Men Are Saying... This may not be easy. We will hear things that we don't want to hear and we will have to accept things that may sound sexist and annoying. None the less - They will still be true!
If you ask your girlfriends or go through women's magazines, you will find that this is how to act on a first date:
1. Don't order pricy drinks or food.
2. Act like someone who will get along with his buddies
3. Don't wear anything too exposing and revealing and never use any curse words - so he knows he can introduce you to his mother.
4. Don't talk much and if possible don't talk at all - just listen.
I am sure you have heard this advice before, right?
While these tips can be good for some type of men, they are hardly the things that will affect his first impression of you (which of course is the most important one)
