The difference between love and sex

SuPeRuNkNoWn1

I am happily married for 30+ years with 4 children and a wonderful wife. I got married young and had only a few other girlfriends before I met my wife. I want to experience a threesome before I die. I have expressed this to my wife but she has no interest in participating. I am not looking for girl on girl, just for two on one (me). I will always love my wife but I believe I can separate a physical sexual experience from love. This would be another life experience similar to bungee jumping or zip lining. My time is running out.

Question is - do I risk my beautiful happy life for a physical experience that is meaningless relative to my relationship.
