I made out with my best friend at a party
Why would you want to make out with your best friend?
He looked so hot at the party that I just couldn't resist myself
It's possible you've both made a mistake. If neither one of you really wanted to do that, it could become awkward for your friendship. It's best to stay clear of each other for awhile.
It's kinda hard to stay away. I'm so attracted to him.
Then maybe you two should officially date. Ask him out and see what he says.
