Replying to Help with google chrome

ive been browsing the internet and cant find an up to date answer for my problem, so hopefully someone here can help me.

i use Pandora a lot for listening to music, and i also happen to browse Pornhub occasionally for personal entertainment. its seems to be the case that i have entered Pornhub.com into my browser more than i have Pandora.com, so now whenever i want to use Pandora i hit P and then return, and feel horrified when i am presented a page full of "sweaty and ready Russian housewives." so my question: is there a way to turn off auto complete, or remove a specific website from my history? i dont want to delete my entire history because then i would loose all of my autofill passwords and bookmarks.
