What the other guys are talking about is something called "systematic desensitization" where you slowly work your way into the target area you are having trouble with. Perhaps one of the easiest ways to conquer any fear or anxiety you may have. Many individuals knock the idea, but it is perhaps the best way to address any fear that you may have. With that being said, you must be fairly consistent with this approach and work diligently. Results only come after exposing yourself significantly to the "target anxiety". By building new experiences you will lessen your anxiety with the given situation and deal with it more effectively in the future.
There is nothing to be ashamed of. Plenty of men have anxiety of beautiful women. It is a natural instinct. It takes some time getting used to. That is why many advocate, go out and do. I actually agree with this tenant of PUA. Go out and form new memories based on a new set of beliefs. And slowly “sensitize” yourself to beautiful women. If you do this, you’ll be alright with women in no time, trust me.
