A couple of years ago I was having the same problem. I had the equipment and intended to ride at night, but just couldn't quite get myself to do it. I posted a thread on this forum about it and got some great advice. The most helpful advice was to go out in my own neighborhood for a short ride during a low traffic time. I did that several times and steadily grew more comfortable. I also would ride my regular commute route during the day time thinking about what each piece of it would be like in the dark. Eventually, I jumped in and did the full commute in full dark. It was liberating! I'll tell you what: I realized that I am way more visible at night than I am in full day light.

Also, no balls required. Ovaries worked just fine for me.
