Girls what you prefer:tough boys-sweet boys-shy boys-romantic boys?

I would say a combination of all 4

starting with toughness - it's always good for a girl to know that her guy will be able to protect her and stand up for her if something comes up, but be careful though, never pick a fight with someone else because you will come off as violent which is never a good thing.
Sweetness - this is a big one, because after all, what girl wouldn't love a guy that brings her soup when she's sick, or gives her a hug after a hard day. It doesn't have to be something big or expensive, you can earn brownie points just for showing that you care :)
Shyness - let's look at it this way. I would be suspicious of the bold guy who knows exactly what he's doing because he's probably done this several times before and is probably a player. If a guy were to act nervous and shy around me I would take it to mean that he really likes me and doesn't want to mess things up. See what I mean?
Romantic - I think this one speaks for itself, but just a word of caution: some girls have different ideas about what's "romantic." I for one, am not a fan of the expensive jewlery or candlelit dinners. I'm more of a "sit on the couch and watch AFV" type of girl (maybe I'm just weird):P My suggestion to you would be, if you have a girl in mind, to ask her what she would consider romantic and keep that in mind next time a special occasion comes along :)

I hope you find my extensive rambling somewhat useful :P
Good luck :D

i perfer a combination of all of those.

I am a boy, but I like boys so I will still answer the question. I like sweet, shy boys.

a tough guy can be sweet sometimes, or shy at times, and romantic most of the time. A combination of all of that is fantastic! got me dreaming of him now :) sigh

Why did I get down-rated for this answer? It seems like a fine answer to me.

Well I would have to say they have to be tough in a way I want some one that can keep me safe ,, and you have to have
sweet and Romantic...I think all girls like that :)

they shy thing to much at lest not for me

but I know every one gets shy at one pont in time

I LOVE romantic/sensitve/a little shy boys! Just someone 2 talk to but must have a little rebel in him

I like sweet and romantic boys. They are interesting !

to be honest i like all the combos of the types u just named. But all they have to do is treat me like they love me , treat me rite and stay loyal/trustin to me.
