First off I'm not looking :3 Sorry Guys! Second I'll answer ur questions personally (the Dark Red) and what I find my Girlfriends (the purple)look for as well, Just because I feel sorry for a lot of guys who sit at home feeling sorry for themselves (I have a few brothers, and lots of guys friends), not all girls are shallow b*tchs! so there is always a chance.
If a guy was to meet you for the first time, how would you want him to approach you?
Personally: I would like a guy to approach me and say a cheesy funny line, or a joke and then introduce himself. I would also find a gentleman attractive, have him hold open open a door for me or escort me across the street.
What I find: My Friends look for a guy who looks after himself, like not having greasy hair or dirt in their nails. They also like introductions first and jokes after.
What could he do or say to get your number or get a date?
Personally: He would somehow have to get my trust, and prove he was interested in me for more then my looks. (boys use ur imaginations U_U)
What I find: Same as me, girls are careful nowadays and try to keep creepers at bay, ur more likely to get a email address to keep conversations with them, just try to be yourself.
How would you want him to speak to you?
Personally: Respectfully and casually, I like feeling like one of the guys but I hate being looked down on.
What I find: Equally, and they like compliments every once in awhile but over complimenting tends to cause them to wonder what ur up to and they start to doubt and disbelieve them.
Where would be the best place for him to make his move?
Personally: for everygirl it's different, so unfortunately I can't help, but if you know the girl well enough to think u feel like dating you should know where :3
What I find: same as above
What would you want him to wear?
Personally: Anything he wants lol
What I find: they prefer them dressed lol
If he had a puppy would that help?
Personally: lol I like puppys but he doesn't have to have one lol and I wouldn't suggest getting one just to pick up girls, I would find that horrible T.T
What I find: lol most my girlfriends like cats more XD, but a lot of girls like guys who have a soft side, which is shown through puppys lol
If he brought you roses, or a drink, or underwear garments would that help?
Personally: Roses, drinks, chocolates and trinkets are always welcome :3 though I would suggest until u get into a serious relationship to keep away from underwear garments.
What I find: Same as me lol and depending on what mood they are in certain gifts can be disastrous!
Example: They are having a "fat Day", do not give them chocolates, drinks or clothes, they will probably feel insulted and think ur calling them gluttonous or fat...
flowers are a fairly decent gift, but not all girls like them, and if they r allergic that could be awful...
As a teacher of mine used to always say, "sparkles make the world go round" lol tho if ur broke even little trinkets can make a girl happy.
Though the best advice I could give is to be yourself and to get to know the girl first, and be her friend.
