It sounds like your looking at guys and acting upon your sexual urges with men to satisfy your curiosity or to fulfill a sexual desire that's not getting met through other sexual encounters. Does this mean your gay? More than likely not, but probably more leaning towards the bisexual spectrum.
However, here's a couple of questions to get you thinking more deeply about your "Am I gay?" questions.
Do you feel more emotionally attached to men or women in general?
Can you envision living your life and having an intimate, emotional, ongoing relationship with a man?
Do you find yourself acting out more sexually with men or women?
How does having sex with a man make you feel? How does having sex with a woman make you feel?
What are your feelings and beliefs toward homosexuality?
Hope this helps!
