Kelsey Paine from Billboard gave a positive review for the song, saying that: "Robin Thicke delivers his signature smooth talk on "Sex Therapy".

Producers Polow Da Don and Hot Sauce set up a languorous backbeat with understated synths and soft drum kicks, while Thicke turns the heat all the way up.

The come-hither lyrics, accompanied by Thicke's breathy falsetto and deep bass undertones, give the song an unforced eroticism that feels ideal for lovers of romance.

"[4] The official remix features Ludacris and a short intro by Polow Da Don and was released December 17, 2009.
