I am unsure if that is completely true as my past experience in the lifestyle was that everyone was very on top of regular STD (think you meant this not SDI) testing and safe sex practices to protect all involved, whereas normal dating there is a lot less of that plus secret polycules you are not even aware you are in (cheating). Not seen a study on this but this was my observation at least.

For the meaning in life to is explore and play with my best friend…my wife. Even my career has switched to something that feels more like play than a grind for a corporation who enjoys the lion’s share of my labour.
