”恥ずかしい”　です!!!
for example, if you tried the new dress in the dressing room and your friends said show me but you feel so embarrassing. you can say "恥ずかしいから見せたくない～<img alt="" src="http://www.italki.com/fckeditor/editor/images/smiley/msn/regular_smile.gif" />". it means "im embarrassted so i don't wanna show you..."
