Is anything a married couple does sexually okay because of the fact that they're married?

I was told by a friend that anything he does with his wife is okay because they are married. I always thought there were some sexual practices that are not appropriate even if married.Is anything a married couple does sexually okay because of the fact that they're married?
as long as they both agree to it anything goes... well having sex with a third party outside the marriage is a really bad idea but if they both agree then its okayIs anything a married couple does sexually okay because of the fact that they're married?
This is all opinion. I agree that so long as everything is consensual, it's all okay. In fact, I think a huge bonus of being married is to have a trusted person to explore all of those wild, crazy fantasies we have floating in our brain.
As long as you both agree what you do in private is your own business. But you need to know that if one partner is unsure it could change your relationship.
As long as it's consensual and they are both enjoying it, marriage or no marriage, anything goes, and enjoy.
No farm animals/equipment,minors,or unsuspecting guests
What 2 or more consenting adults do behind closed doors is their business.
As long as you both agree you 2 can go f*ck goats together...
