I want you to know that I have a boyfriend that I haven't told my family about.
A secret, huh? Why haven't you told them about your boyfriend?
I'm afraid that they'll judge me for being in a same-sex relationship.
I know you're afraid of what your family will say about your sexual orientation, but you should tell them the truth. Keeping your identity a secret will not make you happy. You should be honest with your family.
I'll tell them when I'm ready. It's okay for me to be in a relationship but I'm not ready to get judged for being in a relationship with another man.
Sexuality is a really tough situation to deal with, and I'm really glad you are comfortable with who you are and what you like! It's okay to keep it a secret for now, because it's such a big reveal it needs a lot of emotional preparation for you and your partner.
