I started when I was 10 years old. Basically, I used to just twirl my penis head and thought not much of it.
When I then turned 12, I started getting boners and found it kinda itchy. The more I scratched it, the more it felt good and then I started rubbing it. I went on and on for a good number of minutes and felt weird like as if I needed to pee but since I was alone I said ah well, and just carried on. All of a sudden, white stuff shot out and I was stunned for a minute.
My parents started becoming curious about me taking long showers and eventually, found out. My dad gave me 'the talk' about growing up and doing it privately.
Growing up, I go to massage parlours and get excited especially when the finale is near. There's one place I go to I enjoy because of prostate massage while he strokes me to orgasm which simply takes you out of this world.
