there's full frontal nudity but it isnt sexual

Unless your idea of sexual is a married couple silently slow dancing with one another, there is none

The attractiveness of a behind is commented on, mainly in a joking manner

There is no sexual content in this show.

There is no sexual content in Harry Potter and the Philosopher's Stone (2001).

No sexual content but a teenager is implied to have masturbated in the bathroom. None of this is shown on-screen.

In a scene in the beginning, a man clearly wants to have sex with his wife. She doesn't, and the subject is changed. Nothing sexual is ever on screen.

there is a naked skeleton, but technecly ALL skeletons are naked so i guess not

This is a show aimed at kids, so obviously there isn't anything explicitly sexual, but innuendos and adult humor are fairly frequent. Very mild nudity in nonsexual contexts is occasionally seen, and puberty is sometimes referenced as well, to name a few.

B*****s aren't "sexual content". They are body parts. You're looking for nudity. And also, b*****s isn't a freaking swear word. You don't have to asterisk it out.

A teenage girl sneaks into a teenage boy's tent at night; he is waiting for her in a mildly suggestive pose. Sex is implied, but kids would probably miss it. A teenage couple cuddles on the couch; again, sex is implied in way that kids would probably miss. Multiple instances of kissing. Multiple instances of a character being clearly attracted to another character (getting flustered, blushing, staring, flirting.) Some cleavage shots & cheesecakey swimsuits.

Breeding is very chaste. The two characters just have hearts above them and run into each other to make babies.

Your character can get married and have up to two kids, and your farm animals can get pregnant, but nothing sexual is explicitly mentioned, and nothing is shown. The two closest things are where you can retrieve the mayor's lucky purple shorts" which turn out to be in a woman's bedroom, and an optional cutscene where you find a shopkeeper's "secret stash," though it's undisclosed what that stash might actually be. (I thought it was money or some kind of innocent guilty pleasure, like hidden snacks or a book, when I first encountered it.)

No.

Only in talking and quite vague, but it’s there. Past sexual assault is suggested in conversation

Erik and his girlfriend make out for a couple seconds.

A character mentions that he's had sex once. Two homophobic boys crudely act out having gay sex in front of the whole student body. Sexual innuendos are made occasionally throughout the film.

There is a mildly sexualized character, but it is not done so in a creepy fanservice way.

Makeout scene but anything else is off-screen/implied cos PG-13 age rating

Vague heavily implied near rape but no nudity
