Hi there 'nomorebreaks!'
The only time I visit Yedda is when someone I know sends a question . . . pleased to see that you are still here.
This is my opinion and that of a mother and a retired physician.
With continuing research, there have been no definitive factors involved:
1) DNA testing has no relevant significance
2) hormone levels are WNL [within normal limits]
3) peer pressure is not involved
4) environmental factors, to include opposite sexual abuse, remain multifaceted
These are known's and still there are no documented answers to the question of homosexuality vs heterosexuality.
How would I react? The one thing that I would NOT say is: "I do not want to hear anything else about this kind of behavior!" All that does is create a breach in communication and trust. An open discussion is preferable and needs to acknowledge the issue as one that remains controversial. Parental openness is needed and depending on the circumstances, an ability to accept a decision and not reject the confidential trust of one's child is imperative. My opinion? I would continue to love and be supportive without being judgmental.
Personal experience? When my older son was in college, he had two homosexual 'housemates' and two heterosexual 'housemates.' There was no sexual involvement between any of the five 'housemates.' My one concern was HIV/AIDS, so I used that as an opportunity to discuss hygiene and stress the risk factors with my son. I knew all four young men and there was always an open invitation to visit or spend a holiday with our family. Twenty-five years have passed and my son is now forty-four years old, married (Ph.D. professors) and has two young children.
One of the young men died from AIDS before completing his senior year in college. The trauma of losing a close friend was more important to my son and other friends than the cause of death.
The factors listed are easily validated and my own opinion is just that, nothing more nor less. I am stating my own opinion again: I would try to maintain openness/trust with my child without being judgmental -- I would NOT stop loving my child and I would be supportive in any possible way. Counseling is available through MHMR and parent/child need to make that decision based on a mutual understanding. Parents may need counseling for themselves but I do not recommend an intervention that requires counseling for the child. Teenagers have enough stress factors and that needs to be taken into consideration . . . certainly their well being, both emotional and physical, should be tantamount in any decisions.
I do hope that this answer may be helpful to you ~

I was finally able to post this as an answer instead of a comment.
