Your son is bisexual any advise?

Don't do what my mom did to me. She got mad and told me that I was a disappointment and it completely destroyed our relationship because I told her. I don't think that she realizes how difficult it was for me to tell her. Just tell him that you love him no matter what his sexual orientation is. No matter what, he'll always be your son. So accept the fact that he is bisexual.

How old is your son? If he's a preteen or a teenager, it might just be that he's "curious." Down the road, he may be completely straight, but for the time being, he's just full of hormones that is confusing him.
