You all know what this is about

What if you simply don't use any labels at all and just experience your attractions without defining yourself, or at least until you feel comfortable enough to choose one?

 

One clarification that might be helpful: People don't "go straight to gay". Sexual orientation doesn't actually change; it is just that, for those of us who are bi or gay, it often takes time for us to come to terms with the idea that we aren't straight... because society still assumes that people, by default, are straight... and there is still a lot of judgment my some people (thank you, religious bigots) toward gay people.

So above, you say in the first line that you are straight, but in the third line you say you are probably bi. What you are likely experiencing is your own mind's processing of the idea that you may not be straight. When we begin to accept any loss (in this case, loss of identity as straight), there are stages we go through: denial-anger-bargaining-grief-acceptance. It can take from minutes to years to go through the stages, and they aren't always sequential.

So here, it is likely that you are 'bargaining'... acknowledging that there is some attraction to guys, but not wanting to fully accept either that you are attracted to guys and girls, or that the attraction could be mostly or almost entirely to guys. That's normal. No rush, and take your time with it.

One thing you can do is think about your fantasies when you masturbate without porn. Does your mind wander to fantasies about women more than men? men more than women? Do you find that your orgasm is more intense when thinking about one vs. the other? This, more than most anything else, is usually a pretty good indicator of where your actual arousal and orientation lies.

If you are comfortable experimenting with this and then sharing what happens for you, that could help us to best help yourself understand where you are on the spectrum of sexual orientation. There is, as Chiroptera said, no rush to accept or use any label, and i also understand that it can be helpful to have an answer... so being patient may be helpful here.

 

You shouldn't have to watch gay porn to be able to picture it; you can simply think of a guy (could be a celebrity, or someone in your school or work) that you find attractive, and imagine being with that person in whatever way you find arousing... kissing, mutual masturbation, oral, whatever is arousing to you... and see where it leads you.

For most people, even if they think they have no problems with identifying as gay, usually there's a deep-seated fear that may not even be conscious, as society still puts a lot on gay people in terms of negative stereotypes, religious bigotry, etc. So don't discount the fact that there is likely some part of you that really would rather not be gay, and this can get in the way of accepting yourself if that is, in fact, the end of the spectrum you're on.

So giving that a try may help you clarify. And, again... there's no urgent need to figure this out right away, you can certainly take as much time as you need in coming to clarity on where you are.
