The first step in the development of sexual orientation in gay males and lesbians as described by Savin-Williams and Diamond is during early adolescence, which is a time when they become aware of their attractions and start to recognize their sexual orientation.
Step-by-step explanation:
According to Savin-Williams and Diamond, the first step in the development of sexual orientation in gay males and lesbians is during early adolescence. During this time, individuals become aware of emotional, romantic, and physical attractions that contribute to their sexual orientation. It is important to note that the awareness of one's sexual orientation occurs without the need for sexual activity, and people can acknowledge their orientation even if they choose to be celibate. The process of discovering and accepting one's sexual orientation can vary greatly among individuals and is influenced by both internal and societal factors. Furthermore, individuals may question their sexual orientation due to societal biases and personal confusion, making the journey to self-acceptance a challenging one.
