So I'm a bisexual 21 year old cis male. But about 5 people know I'm bi.

I've got a weird sexuality history. I believed I was straight up until I was about 13. Then in middle school I had a crush on a guy in my class. So my impulsive self decided to tell one of my female friends that I thought I was gay. She immediately told 4 people. After I told her that class (ONE HOUR LATER) everyone in my grade that I knew, learned i was gay. I stuck with the story even though i liked girls and guys.

The beginning of Freshman year I becoming friendly with this other guy in my grade who is also gay. We hit off become really close and and go on a couple dates. At one date we even make out and get a little handsie. He ends up being a jerk and we stop talking.

Fast forward to April of Freshman year. I start talking to this new girl in the grade ahead of me. She comes over to my house and we play the Wii and we start a movie. We cuddle a little and end up having a full make out sesh. We start dating. Break up 3 months later. Then I date 2 girls and talk to a couple for the rest of highschool. No boys.

So everyone in my grade just assumed I'm straight again and no one talks about when I was believed to be gay. Now that I've had time to develop and experience things I know for a fact I'm bisexual.

Now in the present as an adult I have 2 beautiful boys under 2 years old, and a lovely fiance. She knows I'm bi and she is cool with it. But none of my best friends or family knows I'm bi, they think I just went through a weird phase. Would it be pointless now to come out to people even though I'm in a happy, lifelong relationship?
