Dating tips:
Meeting them: two of the women you meet through missions, but for the rest, you are on your own. Go to the place where she is, she will have a blure arrow over her, and walk up to her, and follow the on-screen instructions (sorry i don't have any experience of what happens) you will be either rejected or accepted.
Sex Appeal: every woman loves a sexy man, make sure you're packing lots of it if you want to date one of these women, but nice clothes (not something form SubUrban), cut a nice cut, get inked up, and of course, roll up in luxury. Cars make for a big portion of sex appeal, so make sure you don't roll up in somehting like a mulit-colored Clover, and make sure it's not been in a few wrecks, try to drive cautiously after you jack that ride you plan on taking to her house. Sex appeal works like this, 60% is clothes and 40% is your ride.(goes by the last car you stepped out of).
Pick them up: to initiate a date, either you will recieve a phone call, or oyu can go to her house, (the heart icon on the map) when she is available, and go into the red marker.
Suprise her: there are 40 flowers scattered across San Andreas, pick up one and suprise her with it for extra loving. use L1 to give her the flowers. Dildos have also been reported to work. I have heard of one being in the bathroom of the Los Santos Police Dept.
The date: okay this is it, the big moment. when she get's in the car, she will let you know what she likes and what she wants to do. you will have a variety of options, such as fast food, resturaunts, clubs, bars, all of which will appear on the map. during the date you will see a message saying press L1 to kiss, if successful, you will add 1% to your progress with that girl, L1 also gives her flowers if you have them, which is another 1%. a sucessesful date boosts your progress up 5% with her.
Pay attention to her: If you ignore her long enough, she will dump your ass, and then it's back to your right hand, you don't want that do you?
My Personal Experience:
I have only gone on like 3 dates with Denise, and she likes doing drive-by's, and is down with any place you go to (bar, fast food, club, etc...)
But the game tells you everyhting you need to know when you start the date, so dont' worry.
MILLIE PERKINS: Okay, the strategy guide was wrong on the time available for her in my game, I stood outside her house for a whole day, and she was available at 12:00 noon on the dot, not what the start guide said. So maybe it varies from game to game. She likes, to go to the Coq Resturaunt, and she likes going dancing I noticed. And the Gimp suit IS NOT necessary to go out with her.
have fun, and make sure you wear a rubber!
