the same thing as in sex itself? or having sex with the same person?
Sex can be reinvented in anyway you would want it to be. You could have finish all the position in the kamasutra but it's different with every person.
Some person's missionary and another person's might be different.
But if you are talking abt marriage and having sex with your wife. That's slightly different...i wouldn't call that sex. It's called making love. There's emotions involved. And there's a function too, to make babies.
Would you get sick of your wife if you wake up every morning and see her?
(ok..i can picture someone replying yes to this quetion.

) Theoratically no, because you love her. Practically,i have no idea.
