"I Wanna Sex You Up" is a song by American R&B group Color Me Badd, released in March 1991 as the lead single from their debut album, C.M.B.

"[10] James Hamilton from Music Week's RM Dance Update called it a "sweetly cooing young guys crooned gorgeous sineous sexy swayer".

[11] Stephen Holden from New York Times wrote, "'I Wanna Sex You Up' has a loping pop Latin beat that is similar to the Young Rascals' 'Groovin'' and Laura Nyro's 'Stoned Soul Picnic', and a piercing lead vocal by Bryan Abrams, whose voice resembles that of the late-1960's Stevie Wonder.

"[12] David Fricke from Rolling Stone declared it as "a crafty blend of doo-wop doo-wah and hip-hop clatter so irresistible it makes you willing to forgive the utter banality of the lyrics.

"[13] Mark Frith from Smash Hits felt that Color Me Badd "sound excellent" when "they do manage to break into a sweat", like on "I Wanna Sex You Up".
