What was your first orgasm like?

Without going into graphic details or story telling... What was your first orgasm like?

Was it dry?
Was it wet?
Was it unexpected, did it startle you?
Or was it enjoyable the fist time?
Etc.

I'll start out:

Just before we turned 12 me and my brother asked a cousin who's a couple of years older than us what "jacking off" was. So he showed us by masturbating with us teaching us how. No one touched each other or anything like that, it was just a lesson. My first orgasm was dry and it was a really fantastic experience.

Your turn...
