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?
There is a summary of this article at the end. If you are in a hurry or only a little curious, jump to the last page and scroll down.
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.
Setup Instructions
This can get complicated, but I’ll keep it as simple as possible. (Unfortunately, the best online guides I’ve found are in Japanese/kanji.)The easiest starting point is just the core engine: [PA2] Project Arousal System (v1.0683). Wear/add it. For full functionality, also attach these:
- [PA2] Caeil’s HUD v2 (v1.11)
- [PA2] Chest (v1.671)
- [PA2] Lower Body – No Texture Layer (v1.681)
Once these four are attached, you’re mostly good to go.
Body-Specific Options
If you’re using an Avatar 2.0 or Kemono body, swap the generic Lower Body for the matching version:
- [PA2] Lower Body – Avatar 2.0 (v1.681)
- [PA2] Lower Body – Kemono (v1.681)
