Most Helpful Guy
The only thing "most" guys like from a woman is sex. The reason is because everything is is left up to individual taste which guys can vary a great deal on.
Take for example athletically built girls. Guys have mixed feelings about girls with athletic builds. Some guys find soft curves more appealing than athletic bodies, and that is pretty much a 50/50 split right down the middle as to the ratio of guys who do vs. guys who don't. And among the guys who do like it, there is disagreement as to how much is too much.
Let's look at personality as well. A lot of guys like a girl who can present herself as being "one of the guys" and has a tough edge to her. And then a lot of guys don't and prefer the dainty feminine cutesy type.
The point is, be who you are. Don't worry about what guys do and don't like because regardless, only 1 in 50 men you will encounter in your life are actually compatible mates, and if you try to worry about increasing your appeal, all you're doing is making yourself have to filter through 49 other guys to get that 1 who you would eventually have gotten anyway.
