I kissed a girl who wasn't expecting it.
Why did you kiss her?
I wanted to give it a try. I had never kissed a girl before.
It's great to be experimental, but you shouldn't take it too far out of your comfort zone. Being insecure can make you do a lot of strange things, and in the long run you might do something you would regret one day.
After this I'm honestly ready to try anything.
It's good they you want to fight through being insecure, but you shouldn't use that as an excuse to try anything. Doing things just because you want to get past being insecure is wrong and you should instead focus on things that are reasonable.
