Trust me. I thought I was the same. I even rejected the first time she showed me affection. Takes time, but if she opens up to you and you do the same, there is hope. It's not an easy journey to live through, but you can get some satisfaction out of it. However, dating that person is harder to handle, it's a completely different experience. All I can say is that make sure you are true to your feelings and you don't suppress your insecurities. That's how you lose yourself in the process.
