Girls and women tend to fall in love with images rather than just men, some girls love thugs, others army men, some like only certain races, girls are a lot more fickle about sex and dating than guys (we only care about tits and ass half the time, the rest is negotiable). Muscle and a nice physique do help a lot but I have noticed that the fitness model look is closer to what girls actually respond to, mainly nice arms and abs and you gotta be careful not to over show it otherwise you look like you are trying too hard.
