I am a European ("white") male from Canada, so blending in won't be an option.
We do have white males in Pakistan, so blending in'd be helpful, earn respect and give you an opportunity to meet the locals.
Lahore, seems fine so you could visit it.
It's damn hot in summers, expect 42 to 45 Celsius the average temperatures.
It's the culture capital of Pakistan, must visiting places are
Badshahi mosque, Fort, food at food street.
Avoid visiting the Sufi shrines at rush hours and especially the sufi nights.
Bon voyage..
