What Pakistani guys find physically attractive depends on the person
If you are looking for one look that Pakistani men all prefer, there is no honest answer. Men do not share one type because they share a nationality. One man may notice your smile; another may be drawn to your style, hair, or the way you carry yourself. Someone else may care less about a particular feature than about whether the attraction feels mutual.
Pakistan is a large, varied country, and Pakistani men have different tastes and lives. Age, where someone grew up, faith, family expectations, personal experience, and individual preference can all shape how he approaches dating. None of those details lets you predict what one man will find attractive. The useful question is what the person you are dating likes, and whether you feel comfortable being yourself around him.
