There isn't sin in the feelings. Dwelling on them, fantasizing on them, and acting on them are sin.
From all that I've read and heard from people who have seriously studied the subject I believe it is a psychological issue, not genetic. So, God didn't make you bisexual; if anything culture, life experiences and your reaction to them, whether conscious or sub-conscious leads to it. It seems the things that tend to have the biggest impact is relationship with parents, and having been abused in some way.

Sexual temptations come in all forms.  You're tempted, but you have a choice to follow that temptation or not.  A temptation doesn't make you a sinner.  It's how you choose to respond to it.  Keep pursuing that which is good and pure -- and don't let other temptations side track you.  Remember Eve in the garden?   The serpent said, "Did God really say.... (the fruit's not any good)?" 

Once he got Eve to question what God said (that something forbidden is not good), this was Eve's response,

"When the woman saw that the tree was good for food and that it was a delight to the eyes, and the tree was desirable.. she took from its fruit and ate... then (her) eyes were opened.."  Gen 1:6-7

Be careful, the more you entertain the idea, you can count on it growing more appealing, until you just want to taste it. And then, you will be hooked and what you have now - that loving relationship that God blesses - will be gone.

Just because an idea appeals to us, doesn't mean it's right.  All marriages would fail miserably if we went with that.  Instead, we choose what we value and nurture it, protect and make it awesome and wonderful!

@faithbarista - agreed

Whether you can be born of verisimilitude of sexualities isn't the point. If it turns out you're bi, then God wanted it to happen.If he really didn't want you to be bi, then you won't be. I think Christians believe things happen for a reason, so let that be it.

And that's what college is for  "Experimentation" and stuff. (I'm a boring kid, so I'm still a goody two shoes.) And if you don't want to be in a relationship with another women, then don't! Just because you have feelings toward women that seem strange to yourself doesn't mean you have to do something about them if you don't want to.

Why am I the only one saying all these "Duh!" facts, ehm?

I have gone through the same thing. I always had crushes on females, growing up, but I grew up in a fundamentalist Christian home, so the thought of being bisexual, or being sexually attracted to them was not even something I considered (or let myself consider). It wasn't until I shed a lot of that close-minded behavior, and became sexually active in my late teens that I realized that my sexual feelings were not only confined to men. It was hard to come to terms with at first, but at the end of the day, I'd rather be at peace with who I am, than worry about being judged by others. It's up to you if you want to act on any of your feelings- as long as you remain in the church, you will probably experience too much guilt to make it truly liberating. I had to leave the church to have any sex, homosexual or not, because my guilt would have been unbearable. I'm much happier now, and married (to a man), so it's not as if my bisexuality took over my life. But the fact that I've accepted it as a part of who I am was a very important step in my life.  

It happens.  I've had some girl crushes, but I never acted on them, so they never went anywhere.  Ask yourself, are you happy with your boyfriend?  I think that's what it comes down to.  It doesn't matter if you're attracted to boys or girls, as long as you love him.  

I'm not sure what God thinks, but I know He wants you to be happy.  So, for now, no worries!  If things change, well, you can reappraise when you get there.

If you decide to marry, then you've chosen to express your sexuality with one person for life.  I don't see that it matters what form the other options that you could choose to act on if you wanted take.  Trust yourself and your God.

@Broken_Beautiful@xanga - I think they were more confused about her saying, "The feelings aren't extremely strong, and the idea of kissing a female or even holding hands with one in a sexual way is unappealing."

Of course, having a certain kind of desire on a regular basis doesn't mean God intended for you to have that desire.  The course of Nature has run quite amok from what God wanted.  People have habitual desires for lots of things that aren't good for them.

I really think everyone is bisexual to a degree, they just don't admit it to themselves.  It's not hard to be attracted to different sorts of qualities in the  different genders.  The point of the marriage, though, is that it's good that all the qualities of a man and all the qualities of a woman unite in the ultimate relationship. 

@Broken_Beautiful@xanga - But here's the thing. You're saying you wanted to be sexually intimate with this girl. The author of this article doesn't. I know bisexuality exists--I have it myself. 

@Shy___Away@xanga - I'm glad you embraced yourself for who you are. A lot of fear in religion is you believe what you know, what you grew up in and around. A lot of people could not do what you have done. 

whenever you feel homosexual thoughts watch this video, it will help you quite a lot I think
