It was my 20th birthday and my g/f at the time(she was 16 or 17...I'm thinking 17) thought it would be interesting to see if my penis fit into her.....so we tried.....it wasn't that great but I lost my virginity so I was happy......then about 12 hours later at night we did it again and it was 10X's better.......and then it got better every single time.....we dated for two years(we waited around 6 months) and I miss her alot....but were still friends now....best birthday present I ever got and most likely will ever get.
