UltraSex is the debut studio album by American electronic music producer Mount Sims.

Christian Hoard, writing for Rolling Stone in 2002, gave the album a rating of three out of five stars: "Without the hooks or sense of humor of other electro revivalists such as Detroit Grand Pubahs or Fischerspooner, the L.A. band is left to its own slinky devices, which in fact works pretty well on 'Escape Hatch,' whose silly let's-slip-away fantasy is actually improved by its cheapness.

Elsewhere, the dark, minor-key melodies sound like afterthoughts.

"[5] Bradley Torreano of AllMusic rated the album four out of five stars, writing, "The lack of personal lyrics may leave some cold, but the raw sexual honesty of tracks like 'Come and Get It' don't require any introspective touches to remain effective.

In his debut album, Mount Sims manages to kick down some boundaries and offer a throbbing, sensual slab of neo-electro that isn't afraid to offer some self-aware laughs.
