I can't find where the Bible condemns such things, so long as they're practiced consensually within the context of marriage.
So in your view, so long as there isnt a specific Bible verse that says no branding your wife and its consensual, its OK?You approve of fisting, whipping, branding, and otherwise brutalizing a lover? Personally, I do have a problem with the content of the classes, they are immoral.I can't find where the Bible condemns such things, so long as they're practiced consensually within the context of marriage.
I guess I take a bit different view of morality, and dont require God to provide a laundry list saying no branding your wife, in order to recognize that such a practice violates her human dignity.
I also require a bit more than mere consensus to believe the act is moral. Two people can agree that the first should kill the second, but it still is murder, and still (in this case) violates explicit commands in the Bible (since you seem to be bringing that book into the discussion).

9Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, 10nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. 11And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God.
13 Now the body is not for sexual immorality but for the Lord, and the Lord for the body. 14And God both raised up the Lord and will also raise us up by His power. 15Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a harlot? Certainly not! 16Or do you not know that he who is joined to a harlot is one body with her? For "the two," He says, "shall become one flesh." 17But he who is joined to the Lord is one spirit with Him. 18Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body. 19Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? 20For you were bought at a price; therefore glorify God in your body
If you don't see the obvious inconsistency of those words with the degrading practices mentioned above, I think you need to have your eyes examined.
