1st kiss - First real "French" kiss was with an older sibling's friend's GF. I was around 13?
1st touch - Was with a girl who lived a few doors down.
1st sex - Was with the same girl as 1st touch. On the floor in our downstairs washroom. She was face down and I tried to enter her from behind. It was difficult to penetrate her so I put some Vaseline on my cock and tried again. This time I was successful but she said it hurt after a minute or two, so I stopped. As I found out later, girls have two holes, but the time I wasn't aware of this. Thus the reason I stuck it in her ass. We were both 12 at the time. lol
1st time hobbying - Some Asian MILF at a MP gave me a HJ when I was 18? Can't remember where exactly.
1st real orgasm - Honestly can't remember that either. I know I used to hump the carpet and pillows in my bed from a pretty young age, maybe 6-7 which continued until I started to orgasm. The gamechanger was when I first jerked off. That felt way better than the carpet or pillows. Age unknown though. Maybe 12-13?
