If you cannot handle (1), then the rest does not matter. People who are not willing to take risks rarely receive rewards, either. For (2), you will need to learn the skill of deflecting male interest gracefully and generously (that means that the guy would not be so hurt by you). The skills comes with age and the earlier you start practicing it, the better. (3) as I think I have already tried to explain to you, if the guy likes you, he would like you, and not your skills/experience or lack thereof. Somehow this very simple, basic, trivial point is not something you are willing to grasp. There is a difference between a job interview and a sexual encounter. (4) if you get to that point, most likely he will not be disgusted, but you can always turn off the lights, too. (5) why? it would be a different person.
