well, mr qatar, u don't need a strong perfume...
for men, what i liked most is carolina herrera...it's around 120-170riyals..
it's smells nice and soothing when u smell it...
it last for more than 8 hrs...but the secret for a long lasting good smell is good hygiene...if just put perfume on without taking a bath, it won't help u, it wud only worsen the situation...plus minimizing your intake of spicy food...coz too much spicy food causes body odor...cheers!!
