How to get over my fear of ?

What you need to do is relax, as long as you look in the right places, almost nothing can go wrong. First you NEED to find a guy with an incredible amount of patience. They usually give themselves away by NOT pressuring you into doing something you're not ready to do. By not pressuring you, they will build your trust and if and when that special moment arrives, you will be completely ready and not nervous at all. DON'T rush something if it freaks you out.
