the word sex is in the title...so you can be safe to assume that this movie contains non-stop sexual references, jokes and situations involving Virgil wanting to get with Kellie

several jokes about Virgil being gay

once or twice we see Dwayne looking at porn-mags (no nudity either time), and one of the times he is masterbating (under the covers)

although no nudity is shown...sex is implied several times (its all offscreen, but you hear about it, or hear moaning)

the 3 girls are in the bedroom talking when one of them walks in topless and in view for several seconds.

Virgil gets out of hot tub and his trunk drop showing his butt

stripper in thong showing butt removes her top showing her breasts.

'Fuck' is used in reference to sex. Some derogatory terms about overweight people.
