Is it normal that i started touching myself sexually at the age of 11?

That's basically the exact time everyone starts. Perfectly normal. What would make you think you are gross?

It's very normal, and it's good for you. Your pleasure nerves are still forming connections, so you're basically training your body to get better at experiencing sexual pleasure which will make sex a lot more enjoyable for you in the future.

Masturbation is good for you and it feels awesome, don't feel guilty or ashamed. I say do it as much as possible whenever you feel like it!

defo normal! i started far earlier although i wasn't aware of the sexual implications.

People start touching themselves when it feels good. When it feels good, you are ready for this type of activity.

Ironically I started doing that at the same age and now I'm 23 so when my bf touches me on my clit I just about faint because he's so good at pleasing me there.

A fairly late start, but there's nothing wrong with self-pleasuring.

very much normal

So normal.
