Do you find it difficult to call other people "beautiful"?

Do you find it difficult to call other people beautiful?
Or overall compliment their appearance?
I'm notoriously bad at complimenting people on their physical appearance - I can and do take note that they are attractive, but when I compliment them, usually I compliment their clothes or accessories.
I'm trying to overcome this flaw because I fear it makes me look conceited and I got told that the lack of compliments on the physical appearance makes people feel unappreciates and unwanted.
