"Adolescent Sex" is a song by English new wave band Japan, released as a single from their debut album of the same name in 1978.

[1][2] The song was first released in Spain in April 1978, with the B-side being the band's previous single "Don't Rain on My Parade".

[7][4] Reviewing the song retrospectively for AllMusic, Amy Hanson wrote ""Adolescent Sex" flays wide into classic funk bass-beating thumps, glammed out guitar, snotty punk vocals and proto disco cum wave synths.

Put back together, though, and fed through Japan frontman David Sylvian's pockmarked brain, the song is an onslaught of a bewildering battery of stylistic nervous breakdowns, all so gorgeously twined that the resulting brew is simply stunning".

[8] In reviewing the Adolescent Sex album for Perfect Sound Forever, James Paton described the song as "seeing Sylvian regurgitate his mainstay lyrics of love and dancing, twisting them into some punky song about prostitution that marks the return of the siren synth, with Barbieri lending the composition a certain creepiness with his keys that prevents it from falling flat on its face".
