Well first of all don't worry about being "perfect". Just be yourself. If you're nervous and stressed he will pick up on it and he will be too. There aren't really specific rules for dating but I will share my own "rules" for dating with you.
1. Never assume the guy is going to pay for everything. Always be sure you have money with you.
2. Spend more time listening to him rather than talking a lot. Guys find a girl who talks non stop annoying.
3. Don't be loud. Guys don't like that in a girl.
4. Even if he says something you know isn't right or says something totally stupid, don't correct him. Guys hate having a girl correcting them all the time.
5. Act like a lady. Use proper female etiquette. Sit with your legs crossed, put your napkin in your lap, don't burp, don't fart, pick your nose or teeth,etc.
6. Don't try to dominate the conversation. Let him stear the conversation and even if what he's talking about is a total sleeping pill, pay attention to him. If by chance you like sports it's ok to talk about that with him. For some reason a lot of guys find a girl who likes sports a turn on.
7. Make eye contact with him and smile a lot. Even if they're dumb act amused at his jokes.
8. Guys love to impress a girl. They will brag about any number of skills they have, sports, martial arts, etc. Even if they brag about something totally bone headed, act impressed.
9. Guys also like to show off. If you notice him flexing his muscles, etc, tell him he looks good, has a nice body, whatever. Most guys like having their male egos stroked.
10. If you're going to dinner with him eat beforehand. Then order something like a salad or something lite. A lot of guys find a girl who eats a lot a turn off. You can pig out in front of him once he's your boyfriend but on your first few dinners with him don't eat like a horse. And order "neat" food. By that I mean food that's not messy and that can be eaten with silverware. Gnawing on a chicken bone or diving into a pile of ribs and covering your face and hands with sauce won't win you any sexy points with a guy. Also, if you order drinks have a glass of wine or something, not beer. Sucking down a bottle of beer won't win you any sexy points either usually.
11. If you're going to play pool or bowling with a guy, even if you are far better at it than your date, let him win. Or at least don't school him and humiliate him. Guys can be hostile about that.
12. With kissing let the guy initiate it. Allow him to pull your lips to him. And don't be aggressive with him. By that I mean dont grab him by the back of his head and shove your tongue down his throat. Let him be in control. And don't grab his junk. That's fine once he's your boyfriend but not on your first or second date. It's not ladylike. In my experience once a guy gets turned on he will take your hand and put it on his junk himself.
13. Guys like to brag about their dicks. Even if it's nothing special tell him it's nice. And even if you need reading glasses to find it, NEVER tell a guy his dick is small. And god forbid don't laugh at it. Few things really piss a guy off like making fun of his junk or criticizing it.
Good luck.
Oh, and before anyone gets upset by anything I just wrote I point out these are MY dating rules. I'm not saying other women have to follow them.
