Work on your own confidence. I am a staight woman myself and dont see anything wrong with my man admiring another womans beauty as do I. Just know that we are all the same essence; however master your own inner confidence and self acceptance from the inside so that seeking another's attention forcefully will be a thing of the past.
On the other hand if your man is deliberately shoving other womans pictures in your face in order to strip you of your confidence to seek the upper hand in the relationship, then honey, that is not a healthy relationship.
True love, loves unconditionally and seeks nothing in return.
Love yourself, care for yourself and Be-You-to-full. 🙏🌷🙏
