I have a crush on my instuctor at my training camp. He have an idea that I like him but we never push the issue. I just want to be sexually with him. How should I go about this?

That would be a stupid move on your part and his. You do not say what kind of training camp but I would bet there are some regulations about sexual relationships between a trainee and the instructor.

Why do I need to run into this post twice?

Because some post in other areas, thinking that it will catch more responses or different responses. My guess anyway.
