What is your definition of psychology ?

Plz help me. i'm very much confused about my sextual identity.
i have a strong attraction for boys. i watch gay porn movies. had sex with some guys also before marriage. i though every thing will be ok after marriage but thats not the case. i dont really like to spend time with my wife. and i still have strong feelings and attraction for boys. i dont know am i gay?
i enjoy when i spend time with a boy while having sex. but after that i regret for what i did. help me please what should i do.

Okay, I've been searching for help. I have a problem. Let me start from the beginning.
My eldest brother suffers from cerebral palsy, and my entire childhood- my mom did not stay with me (parents are not separated) and my dad isn't exactly the loving type.
I have been a liar (without meaning to) from my childhood, and I have been sexually abused when I was a child (it didn't feel like an abuse, though)
Growing up, my elder brother (another one) kept dominating me or comparing me with my cousin brother who stayed with us. My brother would even force me to do things I didn't want to. He literally used to twist my arms.
Slowly, I feigned love for him. It happened on it's own. I actually believed myself. I knew I found him irritating and unwanted but still I respected him.
The somewhere around highschool, I got into a relationship and got cheated on. Yes, it was my first love.
It hurt. I was in a boarding school, I felt alone but never cried. I tried to take my life for reasons I can't remember. That phase of my life is a blur.
I thought everything would be okay.
It didn't.
My dad took me to a therapist, but my mom felt I was possessed by a spirit.
I'm 16 now, but I still haven't rebelled or gone against my parents.
Anyway, I never met the therapist again but I had to take part in rituals and what not.
Back to my brother, he manipulated me and made me look bad in front of my parents.
Being the weak, submissive sister I was, my parents never thought it was my fault.
Moving forward, he even made me lift up my shirt because he wanted to see my body type. I was obsessed with losing weight, I was dumb, I did it.
Now he would hug me weirdly and said I never hugged him properly. It sounds funny but he said my butt was too outwards, it should be inwards towards the person I was hugging.
Now, back to my elder brother, I know that he is suffering. But he does so many things to get attention. Shouts, screams, cries all day long. I'm suspecting that he even feigns illness. It isn't that we don't love him, we do. We do everything he asks, but still...
My father has never been affectionate. But he has always been there for me. We're good friends.
My mom, I don't know. She always makes me feel that marrying dad was a mistake. We're good friends, but... I feel trapped. Everything I do has to be under her.
I can't do anything on my own.
I feel suffocated.
So, around five months ago, my elder brother died. He was an alcoholic. He hit me, we fought. I never spoke to him again. I guess, I never will. I hadn't seen his face for a week or so, and when I did... I knew it was lifeless but it didn't look that way. I can't accept what happened. I'm angry that I couldn't be angry at him anymore. I don't know.
Now, I'm rude to people. My teachers say that I have lost that shine. My writing suddenly improved. I can laugh but still I feel different. None of my friends talk to me. I only have online friends.
I feel so alone.
Sadly, I think I like it that way.

I m worried that I might be a sociopath/psychopath. The main reason why I think this is because I was very mean to animals when I was kid. I don t know why I was, but I have been reading up on signs of sociopathy/psyhcopathy in children and this is one of the biggest signs. I never got in serious trouble as a kid like in school or anything. I never really had friends, I always stick to myself and would just swing by myself at recess. I started wanting to make friends in junior high though and wanting to fit in more. I just need help because I don t want to be a sociopath/psychopath. The idea of me being one makes me want to cry. I want to be normal person. However, I start to doubt myself and my emotions. Like, "do I really feel this emotion or am I just making myself feel this to try to make myself think I m not a sociopath?" I literally doubt every emotion I feel and every mistake I ve ever made, I connect it to me being a sociopath. Like I said, the main reason I think I am one is because I was cruel to animals as a child and this is a sign. I know I need to talk to a healthcare professional, but don t know if I can handle the truth. I m worried I ll get diagnosed a sociopath, I don t know if I can live with that. I just don t why I was the way I was as a child, that s what scares me. Any thoughts are appreciated.

I just don't understand my "family". I leave my purse and wallet out on the table and they come and go through it. They just pick my wallet up and flip through my check book. And when I said something my grandmother got mad. She just got mad and smarted me off, then walked away. It's like this all the time, it's like I'm supposed to let them run over me and do or say whatever they want about me or my stuff, and if I say anything I'm a bitch or I don't know what I'm talking about. Honestly it makes me sick just to be here. Sometimes I just feel like I can't take it anymore, like my time is over and I should just commit suicide.
