That's true, but I did see what she meant, they had a lot of "near misses" even with a quick kiss, close but interrupted. I don't need to see anyone kiss to know they love each other but the "almost kisses" seem odd.
I think showing couples loving each other in a more mature way, sex, talk, being comfortable just being together without having to put on airs, is nice.
Two other possible reasons for the lack of PDAs and sex shown on the show could be (1) the target audience (oldsters?) may not be statistically very interested in seeing it, and (2) the episodes are short, and PDAs and on-screen sex are really just fillers.
