Some kisses.
There is nothing explicit happens but some innuendoes. There are some uncomfortable positions and situations.
There is one eps that the two couple try to make bed scene together but being interrupted by the male's mom
A guy asks a girl he was talking to to kiss him. The girl becomes insecure and then overcompensates by saying she is more experienced than she really is. So he tests her to see if she would have sex with him for pay instead. He takes out the money and unzips his pants while pinning her to the wall, which he seems to only be scaring her so that she won't get involved in that kind of stuff. And then he kisses her.
A lot of sexual innuendoes.
