So, I am bisexual, and I need advice.
I do have a boyfriend, and I believe that you should have a relationship with only one person. Though my problem is, he doesn't know that i'm bi. I'm afraid of what he might think about me after he knows.
Should I tell him? :gonk:

I think if you want to have a serious relationship, you have to be honest about who you are. If he can't accept you for who you are, then he's not right for you. Odds are, though, that he'll be fine with it and might even spice up your sex life. I think a lot of guys would be excited to have a gf who would enjoy watching girl-on-girl porn with them. Basically what I'm saying is that I think he'll be ok with it and it has the potential to make your relationship more exciting.

If you don't trust him enough with such a great big section of your life, then it's possible that he might not be "the one" after all. ;)

Has he ever expressed any homophobia, or given you any indication that he'd think less of a bisexual person? As long as he understands that you're not about to run off with someone else, then explaining your feelings to him can only help you two get closer and get to know one another better.

I've also gone ahead and moved this into Life Issues for you. Hopefully you'll get some good advice here.

Thank you, guys. I know I should trust him, and tell him. It's just been hard lately, since most people I used to trust rejected me after "coming out".
I will try my best to resolve my personal issues. :)

Tell him... if he can't handle that, he doesn't care enough about you to put it aside...

Plus.. =) be proud of who you are... orientation and all

I'm gonna agree with what everybody else has said. It's better to share something like that with someone you are getting close to or are already close to, now, rather than have it potentially come out later when it could lead to "Why didn't you TELL me??"-type arguments. Think about how you want to word it when you tell him, before you do. Tell him that the reason you're sharing this with him is that you feel safe with him and want to be open and honest in your relationship. And since bisexuality is so often misunderstood, be up front and let him know that while you do have feelings of attraction to people of both sexes, you definitely aren't looking for anyone else, female or male, to be romantic with at this point, because you already have him.

Good luck!
