Retroactive Jealousy is about worrying about the previous sex life of your partner.
It is destructive. It eats away at the person allowing themselves to worry about it. It destroys the relationship.
It is merely a matter of perception: confidence, trust, accepting reality, and looking at and really appreciating the beauty of the relationship you have.
I can help you let go of this and appreciate what you have. This will then let you celebrate and improve on the wonderful relationship you have.
If someone is with you. It's because they want to be. Enjoy whatever time you have together to the fullest. Don't create regrets. Enjoy every moment.
Let me help.
