As long as it isn't a blatant joke name with some sexual reference, I don't care what the hell people name their MCs.
My P3P characters had silly joke names, but not sexual ones. The male was Kei Higashi, written with the characters that form the name Tokyo. And the female was Yoko Hama. So, they were both named after cities.
