I love riding with my guy, but I also have SO much fun riding by myself in which I can go my own pace and try out new things. But, when we do ride together which I'd say is 40% of the time, we go back and forth of who leads. We just have fun with it as you should too. Enjoy riding with your guy but go out by yourself and tear it up girl!!
I've been riding for a few years though, so your fear (as a new rider) is understandable of riding alone.
