It is always an ego boost being complimented for your size, or noticing that in locker rooms jaws drop or eyes stare at you.
Looking at porn and realizing you are on the big side there also, being told it is even too big, feeling your manhood flopping between your legs, knowingg that you are known as a big guy...
Yes, there are many more important things on a man, but hell, this feels good for sure.
