You're fine. Some people don't want a partner with a huge penis. It can be very overwhelming and difficult deal with. I know lots of girls and guys who greatly prefer average size and even smaller.

The color of it doesn't matter either. Most people don't find penises aesthetically pleasing at baseline even if they are attracted to men. I do, but not for their color. The color of it doesn't matter at all. What matters is if the size and shape are compatible with your partner and knowing how to use it.
