Project Arousal is a wild, fun concept for Second Life® (SL): sex anywhere. Want spontaneous, ravishing lust that sweeps you off your feet (and onto the floor) without hunting for a private spot? In real life, that kind of abandon would probably get you arrested. In SL, it’s at worst a ban. So, Project Arousal takes things to a whole new level of passion… or trouble, depending on your luck.
What are we talking about?

Back in 2020, I wrote an article called Second Life: What is Project Arousal? (Review-Tutorial) when I was just figuring it out. The TL;DR: it’s basically a sex toy system. It lets you have sex anywhere scripts are allowed—ideally in places that also permit object rezzing.

Project Arousal 2 (PA2) is a full sex system with tons of add-on toys. The base “engine” supports a huge ecosystem of extras. As of February 2026, the core costs L$2,150 (up from L$1,000 in 2020—not cheap, but you get a lot). By itself, it’s enough to get started, but you’ll probably want more. The creator (Caeil) offers around 78 official add-ons, and searching “Project Arousal” on the Marketplace turns up over 500 related items. Plenty to explore.
A key incentive for its use as a partner can initiate sex by simply clicking the avatar. HUDs are not required once the system is learned. Similar to clicking an RLV collar. Simple.
