i am not taking testicles into the equation
i am going to agree with luci about the pointy penis contributing to ugly penis
I've been told i have good lookin one
Veiny can be fine as long as it's not too veiny.
Obscenely large penises can be disgusting imo
Foreskin is fine as long as it's not fucking birdo cock
If your foreskin not only completely covers your head but actually protrudes another half inch that is really fucking gross
Penises of color are not inherently ugly but are more susceptible to being ugly due to the risk of having some weird color pattern
Obsessively wrinkly foreskin is gross though, forgot that too.
