Your personal, individual, flawed interpretation fails again. What DOES the verse say?

Hebrews 13:4 Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.

It says that marriage is honorable (as it is), it says that the bed should be undefiled (i.e. no whoremongers or adulterers). It doesn't say that the two had nuptial relations -- that's your own guessing on scripture.
