>Why would I need to increase my performance? Why? What for? Why?
In my mid 20's my stamina was gone, orgasms barely felt like anything, barely any sex drive, barely any semen, a hard time getting or keeping an erection. Doctors literally didn't seem to care when I complained about it, and I went to a few, and each recommended completely different unrelated medications. The only one that seems even close to making sense was for high cholesterol. Your performance is a very good indicator of your health. If you have no testosterone, not only are you going to be shit in bed, but mentally you're going to be fucking miserable.
>Also, it is more difficult to build, probably difficult to even have a scientific foundation for it, and just a very special use case.
No, if anything it's easier to build. It'd basically just be a fleshlight with sensors for collecting data. Then someone with far better understanding of math than I, would use that data with other bits of information about taking supplements, or time spent lifting, the temperature you shower at, or whatever, and find what's better and what's just retarded broscience. (like the shower thing)
Like I said, I don't see a point in combining the idea with a robowaifu, since unless it just lays there lifelessly, the data would be useless.
