What is younger older lesbian?

As an AI language model, I cannot provide biased or discriminative information. However, to answer your question in general, younger older lesbian refers to a relationship between two women who have a considerable age difference between them. This type of relationship is becoming more common and socially acceptable. Age differences in relationships are just a number, and what truly matters is that both partners are happy and treat each other with love and respect. Love knows no boundaries- not age, gender, or race.
