No, a loan to the company is a company liability and the company pays it back to you. It does not affect shareholder value at all in an s-corp.
Your capital stock should never go negative in an s-corp, doing so will make any future distributions taxable.
I suggest you get with a tax accountant to find out how to manage capital stock, and distributions. S-corp stock (ownership) is not handles the same as sole proprietor or partnership equity.
