I grew up in a conservative home, where sex was never discussed.
I started puberty but never realized what was happening with me. I noticed hair in all different places even on my upper lip.
I must have had many wet dreams but didn't even know about them.
One day I had a boner as usual (didn't know what to do with it though) and went lying on the bed in the sun. Eventually I took my dick and balls out and had it in the sun. I was lying there and all of a sudden this white goo came rushing out my penis. I didn't know what to do, rushed to the toilet and cleaned up. It was a mess!
About six months later I read up on this and figured out it was semen and how to make it happen again. I have been having fun with my penis since then.
