(my first letter to my name is close to your eye)(the 2nd is around your head)( the 3rd is rated not for kids)( the 4th is "D")(5th is my first which as "a") & (last letter I shall not say).

math equation way= a+b+RD+a+c

The third and fourth letters are RD and the name starts with a vowel. The vowel it starts with is used at least once more in the name as the 5th letter.

So a name starting with a vowel, then a letter, then RD, then the same vowel, then another letter. (note, said letter, not consonant)

Sorry, that's as far as I could figure out for now. I'm also only guessing "which as "a" meant a vowel.

Unlikely Possibilities that Exemplify the Name: Airdan, Earder, Ourdon, Aerdae, Ourdou, Aurdas
