Sometimes when my penis is erect the head area gets a little bit bigger and fatter than normal is that normal?

[SwimTech]

Yes, it is because the spongy tissue in your penis (and head of your penis) is filling with extra blood, which causes the erection

its normal.

yessir. the increase in blood causes an expansion in your blood vessels through out the penis and increases the size and width.
