I believe in loving, dating and marrying one person only. I heard that in US, it's common to have one night stands, friends with benefits. Is it true?

I don't like one night stands, friends with benefits. How hard it is to find a guy who is in US who is my ideal person who has no history of dating, one night stands, friends with benefits, etc?
