First of all, your penis is still considered "average size". So don't get too worked up about it. Secondly, the most important thing in the bedroom isn't penis size, it's communication. Work together, find what she likes, find what you like, let her guide you, it'll be ok.
I don't think many women are too concerned with penis size if it's somewhere around average, especially when it comes to the person you truly love. I've been with men who are larger, I've been with men who are smaller, the man I'm currently with is above average in size, this is true, but I'm with him because he has a wonderful personality. Not because he has a big d***. Trust me, that's the last thing I cared about.
Just keep a good communication going, trust me, you'll be fine.
