spoolworm: I like my penis how it is 8"+, 6"+(21cm, 17cm). Im 6 and a half foot something(I'm a metric person, so 195cm), so it looks a good size.
Bigger would just be annoying when doing sports. I already have enough that most woman won't lack because I'm too small. Besides, it's not 'that' important. I think it's more important for me to have a biggish(8" is big right....correct me if I'm wrong) penis, than for the girlfreinds I've had. There are more ways to pleasure a woman than with your dick, and if you're not big enough you can always buy dildos.
