You need a toy that's both firm and flexible. Doc Johnson has a line called Dual Density. Toys in that line have a fairly firm core with a softer exterior. I've got the John Holmes toy from that line and I can go balls deep with it quite easily.But was there anything besides practice and lube that helped you take 16"? When I see the bulge in her stomach from the tip, I'm amazed it goes that far.
I used to have the Dick Rambone dildo....I think it's 16 inches. I could go balls deep on that one too, but due to it being very rigid (it wasn't a Dual Density toy) it wasn't always easy getting it in completely. I ended up throwing it away.
I think there's a Dual Density version available out now, so it looks like a purchase is in my near future. Originally Posted by john_doe1978
