One of the characters is pretty non-stop in "going after" female characters. By today's standards we might classify this as sexual harassment/sexual assault. The feel of this during the movie is very dismissive. It seems like this is what they expected of him, and what they tolerated of him. During these scenes the character will grope women, grabbing their (clothed) breasts, kissing them, forcing them to the ground, etc. At one point it seems as if he might be seeking to rape a woman, but it is broken up with the arrival of another character. During a couple of these, a woman's nipple is very briefly seen (less than a second), due to her shirt being pulled.
There is a bedroom scene with a man and woman in bed together naked, though they are covered the whole time, and only appear to be kissing.
Woman show cleavage and midriff during most of the movie. Some women wear tight fighting short shorts.
Woman act flirtatiously and coyly towards men.
Women go skinny dipping. They are shown in the water with their chests out of the water from afar. A woman is shown putting on her shorts after swimming and the side of her hip/butt is shown as she pulls them on. She is shown from behind as she then puts on her top.
