Only in the first few weeks. In three or four months, the night of love is already "you that, tomorrow to work for me," in six months, twice a week - it is already "we just fucked." If you take a half-year break - it will be a honeymoon again, and then again, I am so passionate, so passionate, sometimes even twice a month.
Well, if you lie down drunk, stinking, unbarred, and still screaming just sucked, why be surprised?
