Should I feel bad for this?

Hey,

This morning I woke up and went on the chat site "omegle"

I am a twenty year old, and I spoke to a 18 year old, but I said that my age on Omegle was 24.

I didn't really speak sexually to them I asked them one kind of sexual question, if they go down on women...

Then after he replied I exited and I have had a sense of guilt and shame over me since, I mean, in my country 18 is the legal age and I am only two years older, I just feel ashamed, is this wrong?

Definitely not wrong. 18 is an adult and you are only two years older. Totally normal and moral.
