lets say you have a gf/bf and he or she is your first for everything(sex, first kiss, etc). Say you've been going out for 5 years already... and you tell people that she is "the one" and she is "the best". for you guys.. how do you know that she is "the one" if you've never been with anybody else and how can you justify "the best" if you have no prior experiences to compare with? so technically, it wouldnt be considered the best.. it would only be whats you find as satisfactory? same question for girls also. sorry if this question came out sounding bad as i'm not trying to offend anybody.. i'm just curious.
