Some people can, some can't. It depends on one's emotional and sexual maturity. But if a twelve year old girl has zero romantic interest in guys, has had multiple crushes on girls, adn feels in her heart that she is lesbian, then seh probably is. And if you are asking this question for yourself, then congratulations on understanding yourself a lot better than I did at twelve.
tell him the reasons why you are a lesbian...he will understand.
You can tell if you are a lesbian if you are attracted exclusively to other women.
What does that mean? If you need a 12 year old lesbian I am ya girl!
If you are a curious and need to tell if you are a lesbian, think about a woman's body. If it turns you on in a sexual way, you are likely a lesbian.
You ask her.
That your a lesbian
You ask her.
Tell your parents if you have not all ready.A:No, you don't have to tell them yet. Wait till you know lots more about being a lesbian, so you can answer their questions confidently. When you're really sure about it all, and have thought about it, then you'll be much better when you talk to them.
That your a lesbian
Ask her
They can't tell from an exam. The only what they can tell is by asking you.
No, you can't tell unless they tell you, or you find them in a sexual situation.
