Step-by-step explanation:
According to current scientific understanding, individuals are usually aware of their sexual orientation between middle childhood and early adolescence. They do not have to participate in sexual activity to be aware of these emotional, romantic, and physical attractions. Some people recognize their true sexual orientation later in life, in their 30s, 40s, and beyond. It is important to note that the process of questioning and accepting one's sexual identity can be challenging due to societal biases and personal emotions.
