There is no definitive answer to this question as everyone has different preferences. However, some common trends can be observed when it comes to what type of body girls tend to find attractive. Generally speaking, girls tend to prefer guys who are tall, fit, and muscular. This is likely because these physical traits are associated with good health and high levels of testosterone, which can make a guy appear more masculine and virile. Additionally, girls often find guys with broad shoulders and narrow waists to be especially attractive as these proportions are considered to be ideal for child-bearing. Ultimately, though, it is important to remember that every girl is unique and will therefore have her own individual preferences when it comes to the physical appearance of her partner.
