Fear of beautiful girls/women, how do I resolve this?

although i'm not clinically diagnosed with caligynephobia, i do have some affiliations. ever since i was 12 till now i am having constant problems when confronting girls or women that falls into my "beautiful" category. for example, i will get nervous, and my heart rate will increase. in many cases i am suddenly unable to think clearly and i will struggle to remain cool and cover my nervousness while speaking. does anyone have a solution over this. (btw. its more looking at a real person instead of pictures or videos that causes this problem.)
