I didn't start dating until college and my first sexual girlfriend was going down on me for the first time, stopped, looked up at me and said "Wow!". I said "What?" and she replied "You're huge!"
I said "Really?" and she said "Yeah, one of the biggest I've ever had" and returned to giving me head. At some other point, probably in post-sex chatter, I asked about her previous relationships, and it turned out she was quite experienced for someone in their early 20s. When she wasn't in a serious relationship, she tended to fuck any and every guy she liked, just for fun. So I was in her top 3 size-wise of about 30 guys before me.
When I was with the second woman I got the same type of reaction, and with the 3rd, 4th, and so on and so on. Every woman who has experienced my erect penis in any way has commented on how big it is. A few women in my past were sexually liberated and had experienced being with many men over the years. They all put me near the top as well.
When penis size survey results were first published online, that's when I saw that I was in the 93-98th percentile in length (7 inches) and the 98-99th percentile in girth (6 inches). Then came sites like LPSG and
calcSD - Penis Size Percentile Calculator and other that all confirmed the same thing ... I've got a big dick. Not the biggest, but often the biggest most women have seen or experienced.
