Talking to all my bisexual folks
Guys I promise you don't need to hide or give up on your bisexuality in order to be in a loving and fulfilling relationship. Let me tell you:
I am in a ten months relationship with a guy who has never had any contact with anything related to the lgbt community before dating me. Also, he was raised in that kind of family that, like, acknowledges the existence of gay people, but doesn't really care about what happens to them... they are pretty neutral about it.
I admit that, when we got together, he didn't know I was bisexual yet, but I was willing to say it to him one day, hoping that he would accept it, but still knowing that if he didn't I had to leave him.
So, a few days after we got together, I found out that somebody outed me to my bf, without my permission to do so. I started panicking. I felt like a liar and I was very ashamed and sorry for not being able to tell the truth to a person I really cared about.
Then, when we finally discussed it, he said: "I don't understand bisexuality, but I believe you. It's okay for me, I just hope to be enough for you even when I can't physically give you what you need", which is something that impressed me a lot, and made me love him even more. Then he asked a lot of questions about my sexuality, out of curiosity (and of course I found out he used to believe in every single stereotype about bisexuality lol).
But the thing is, even if my bisexuality was a surprise for him, he didn't make a big deal about it, he just... accepted me for who I am. And he asked questions to comprehend my world a little bit more. This is what love is all about.
So, if somebody isn't willing to accept you for who you are, or if they ask you to hide something important about yourself, then let them go. You deserve to be with someone that loves you and cares about the real you. If they love you, they won't care about your sexuality, they will trust you and they will believe you. Don't settle for less than that.
