This is the sort of sexual vocabulary people should be learning instead of bullshit like "ONS". To be friends with benefits is the purest sexual relationship a person can have. You trust, respect, and love your friends, right? Then why not fuck 'em? Because it'll be awkward the next day? Grow up!
Contrast with the transactional "Wham, bam, thank ya ma'am" of a no strings attached (NSA) relationship.
thanks for you explanation after all , dando , really , nice talk.
