Hello and welcome to HealingWell. I think Karen's question is a good one - age depends on a lot of what you can control at this point.
I learned from experience that just because certain people are your parents, that fact does not automatically make them loving, understanding or even nice people. You have your life to live and you must live it the way you choose to in order to be happy and fulfilled regardless of what others think, parents or otherwise. Just remember to choose wisely especially if you are young.
Some teens may also experiment with sexual experiences, including those with members of the same sex, during the years they are exploring their own sexuality. These experiences, by themselves, do not necessarily mean that a person is gay or straight.
I wish you a happy holiday season,
Kitt
