Girlfriend thinks I should tell my mom

Hello ladies!

I hope you don't mind that I'm a man on here. Me and my girlfriend use this to track her cycle so we can avoid children along with using condoms. I know there is a lot of moms on here and I wanted to know if you were my mom would you want to know.

I like to write poetry and music. I've written a few songs and released them on YouTube. I wrote a song but never planned to release it. I sang it to my girlfriend. It was about my dad. My parents have been married for 39 years. They're so close to 40 years. I'm 26. When I was 9 I was with my dad. He was drunk. He used to be an alcoholic. He asked me to come here and told me to take my pants off. He put my cock in his mouth and then made me suck his. It never happened again. He never spoke of it. No talking about it. No apology. Just pretended it didn't happen. My dad has been sober 5 years now. Me and him aren't close at all. When I visit we don't talk much. Just me and my mom. I told my girlfriend what my song was about and why I'll never release it. She said I should and should tell my mom. It's beenclose to 20 years since it happened. This may fuck up my dad's sobriety. So I don't know. Is there a point in saying anything now. It happened once and never again. Maybe I am still in pain which is why I wrote a song. If you were my mom. And this happened once. Your husband is sober now. It's been close to 20 years since. Would you still want to know?
