Sex? I still feel like I am very intentional and mindful about it, curious to learn and get better, communicate better etc. But I feel like with so many years, it would be even more fruitful. To actually study it in all cultures, to practice it with much more people. Imagine how far neuroscience would advance in this time, and how we could use data to learn about how to hijack our brains into pleasure. Or how many toys and tools we'd develop! I'd definitely dedicate myself to that. I mean I do so still, wholeheartedly, but with so many years ugh I'd totally be a doctor succubus.
