Gay / uality question?

Okay so every time I get horny I usually (like 3 times out of 4, but maybe a little less) seem to end up watching gay . About half the time I end up switching it to straight midway through and finish on that, but other times I keep going with the gay and get very up until (I occasionally desire to have the real thing), after which I feel guilty. Other than that, I've looked at pictures of naked men, but it didn't do anything. It only seems to arouse me when a ual act is happening. Now on the other side of the spectrum, I enjoy watching women performing ual acts and I also feel like I could only really have a relationship with a woman. Now, also keep in mind that I have been attracted to only women outside of and I've never been in an actual relationship before. That's about all the details I can figure, do you think I'm gay/bi or just curious? If you think I might be gay/bi, please give advice on how to not feel so guilty anymore.
