Is it normal to be attracted to the opposite sex after smoking pot?

I've been smoking pot for a while now, but it was only recently after getting high, i found myself wanting to kiss another guy, now this completely out of character for me, as a couple of weeks back i would nearly hurl even thinking about doing that. To add to that the guy I want to kiss is bisexual and a friend of mine and now im somewhat attracted to him.
