Twofold

!) I have no reason to be, never has there been an inkling or even any behaviour that would arouse jealousy.  He never looks at other women when we are out and is very much a one woman man.  He never goes out at night with friends, he has had his wild days and now is settled.  Yet, he does have a jealous streak, as that is his nature, but it is over the most random and stupid things, and it does not help when I laugh at them.

2) I am very much Aquarian in my nature in this respect.  I have never had a jealous streak, which has led to difficulties in some relationships as it is equated with not caring enough.  However, it does happen to be apparent in not only my relationship with my partner, but in the past with relationships with friends.  If they won awards at school, I was happy for them, if they got something new, i didn't care, was interested when they were showing it to me.
