Dr. Beth,   I have a son who is a sophomore in college. He dated several girls in high school, only one girl seriously that he dated for about a year.  In college, he has some really good guy friends and other girls as friends too. Last week, he wrote me an email and said he has figured out that he is bisexual. Then he posted a picture on Facebook of him and a guy friend with their arms around each other and updated his relationship status to “in a relationship”. All of his recent posts are about time he and his new friend are spending together doing fun things. Does this mean he is gay? I want to discuss this with him but how do I start the conversation?!?
