I get erections from seeing pictures of girls online sometimes, the same thing happens when I'm at my job, when I see a girl I think is pretty, I get half chub, sometimes full chub. I thought I liked guys, but It's extremely rare, almost non-existent I get boners from them, what gives? Am I suppressing my desires or is it society?
Your dick is a true indication of who you're attracted to. As they say "The body does not lie!" U sound pretty young, perhaps without a lot of sexual experiences. Besides the reaction of your dick, other things to notice are who u fantasize about when u masturbate, what your family situation was like growing up (influences of parents, siblings, friends), & how comfortable u feel around girls or guys. It'd be helpful if u said more about your family situation, & intimate experiences (sexual & non sexual) you've had. Sex & intimacy is often our most cherished thing - may u relax into it & dig it a little more!
Actually erections aren't always a good indication of what attracts you. A lot of male rape victims have gotten erections during the rape, which often leads to the question of whether or not it was consensual (which it obviously isn't). It's just a normal bodily response to sexual stimuli. Like BeingDude said, try to take everything into consideration and be open to whatever the answer may be. Maybe you're romantically attracted to men, but primarily attracted sexually to women. Anything is possible.
BeingDude, well every time I was with my ex-girlfriend, she'd always make me so hard every time I felt her up; I've recently have experimented with my friend who is male, like cuddling, and he too made me really erect. When I masturbate without porn, masturbating to the girls I've known in my life, like from school, get's me going, but then I switch to my friend, and that get's me really going; I wouldn't say my parents are extremely homophobic, they never told me being gay or anything was bad, but certain comments from my dad seem to indicate that he's grossed out by it. I have a brother who is completely accepting of the lgbt community. I'm uncomfortable around a lot of people, men and women alike, due to my social anxiety, but I guess i'm more comfortable around men compared to women.
Maybe you're just bisexual if you've had attraction to both males and females. Perhaps you're more attracted to men than women, but that's okay. Bisexuality doesn't always have to be an even 50-50 attraction. I would consider myself 75-25 men to women, for example. It's up to you how you wish to label yourself. However, I don't see any reason why you want to suppress yourself sexually. If you open your mind, you'll have a better understanding of who you are as a person, and then, one day, you can fully accept the real you. Just felt I should clarify, I'm not saying you have to identify as bi, just that it could be an option.
