I'm 17 and I never had a girlfriend or something like that and I think I never will
Have you ever liked a girl?
I'm not interested in girls and I don't think it will change any time soon
It is okay that you are not interested in somebody, you are still young and are still finding out who you are and what you like. You can find a person you like when you get older.
I'm asexual and I'll never kiss or touch anyone.
It's good you are trying to figure out your identity while you are still young and have lots of time to experience. Being a teen is quite tough too, so focusing too hard on relationships can cloud what you want to do for your future. So keep striving for your best and you'll figure things out soon.
