Four topless young women at the end (their breasts are covered by their hair) are wearing small beaded skirts so it is easy to see their butt cheeks or parts of it.
In Will's gift shop, there are several mugs shaped to look like a womans breasts. Will holds the mug up and says, "The perfect woman, a big ol' set of boobies, no head, and a handle".These mugs are in FULL view throughout the scene.
Will says to Dr. Rick and Cha-Ka, "How much will it cost me to have you two french kiss?" Rick then says, "If it doesn't leave the three of us I'll do it right now for free." they then pretend like they are going to "make out" but they don't.
Waking up from being high, Rick, Will and Cha-Ka are laying on their sides holding each other. Will and Cha-Ka are in a position where their faces are in the crotch area of the other one and Rick is behind Cha-Ka.
There's a scene where two sleestak are supposed to be mating, and Will says, " I think he is about to tap that ass" this is said twice. There are some crude terms for sex or sexual content.
When Rick, Holly, and Will are on the hill before rescuing Cha-ka, Rick asks WIll, "Man are you touching yourself?"
When the group is meeting Cha-ka for the first time, Cha-ka grabs Holly's breasts several times and continues to do so throughout the movie. Will also grabs her breast.
Will describes going 6 years without female intimacy.
When Rick gives up on his mission, he lies down and tells the group he is going to stick his hand half-way his pants.
Will tells Rick and Holly that they are going to get wet. Rick tells him his machinery cannot get wet and Will says "Not you, Marry Poppins. Bow-chicka-wow-wow."
When Rick and Will find a vibrating object, Will tells Holly she should sit on it.
When Cha-Ka refers to sex (in his language) he does pelvic thrusting motions.
Cha-Ka touches Rick's crotch several times in one scene, he then humps Rick's leg.
At 1:31:10-1:31:59, there's a scene where a few semi-naked women walk up to Will and Cha-Ka, but they have something (very small) covering their bottoms, and their hair covers their breasts, however the sides of the breasts are exposed.
