I'm sure he can speak for himself and he has. He has said a whole lot more than just calling himself a "sex machine." Perhaps, compared to his gf he is. The point that I and others have been making is not whether sinking is a perfect human being or not but simply that he is not yet married and if this is a core issue then at the very least any wedding should be delayed pending figuring out how to resolve the issue or if it can be resovled.
Additionally, I didn't pass a value judgement on your youthful choice. Many people make the same ones and a lot of people regret those choices. I just don't equate your description with what sinking seemed to be talking about. I perceived him as describing a high sexual appetite in general that he would prefer to direct toward a receptive spouse. He didn't say that he wants to "f everything in a skirt." Of course, my perception says a lot more about me than it does about him since, as you point out, I don't know him. My perception is there to take or leave - just like yours.
Tamashi - I wish you the best of luck in your personal endeavors and I will assume that you had the very best of intentions in what you said.
