Am I a lesbian or is it puberty?

Also... I have never had a proper relation ship or kissed a boy...I have kissed a girl once but i was 5years old and we were playing High school musical and i had to be the boy, so it doesn't count. I don't remeber enjoying it, in fact I didn't think i liked it, I felt no chemistry towards girls because I was five years old and I just physically CAN'T imagine being in a steady sexual relationship with another female, yet I can imagine being in a sexual relationship with a man.

I doubt I'm lesbian or Bi but I need help soo pleasee answer

Btw in case you don't know this is me the person who asked the question

The one thing you never mentioned is how old you are?

I'm 13, it says

Firstly what you see in that video wasn't really stepmother and daughter they was just porn actresses.
What your experiencing is perfectly natural and nearly all teenage girls and boys in through the same stage its just to do with your New hormones your body is trying to deal with.

You are a girl.

You are lovely.

Think positively about your self.

Ignore negative and degrading thoughts.

You are wonderful the way you are.

You are more important than sex.

You don't need to prove yourself in anything.

God made you.

Don't corrupt yourself

What your going through is not uncommon in teens and especially young teens. Relax and enjoy being young. Heck, I am a old man and the thought of teenage girl licking stepmums is gross to me even....you seem perfectly normal to me.
Have a great life and don't rush into sex too soon. Sex too soon not only is unsafe, but something you most likely will regret afterwards.
