No. I mean… just no.
I would HIGHLY discourage you from doing anything like this.
First of all, let’s talk about the health risks. Branding is dangerous. This is a high risk of infection. You are burning human flesh to make a mark. It is unlikely to be treated properly and medically. Do not assume that there will be instant cauterization of a wound. If it gets infected and festers, you could have long term, permanent damage to your body.
Now let’s talk about how fucking stupid it is. I am sorry. I don’t mean to insult you, but good god. If that is so guy’s version of dominance, what the fuck is wrong with him? “Let me control a boy by placing a flesh burning metal rod on his skin!” What part of that seems legitimate?
It sounds to me like he is messed up in the head, and I would stay as far away as possible. If this is how he wants to “show ownership”, I would bet good money that he will do far far far worse.
I realize there may be people out that think there is nothing wrong with branding, and you are welcome to disagree with me. However, this action violates everything that I stand for as a Dom. It is the work of a fraud, an abuser, and creature that has no self-confidence.
My advice: Get away now.
