Domain help www.gettingnailed.c*m

Hi, i am new to this forum and just come across domain flipping I have many good domain names I have bought over the last month such as gettingnailed.c*m and blackpresident.c*.uk. I was wondering would it be best to sell them, those two are newly registered or is their any other forms of making money from them as I expect they will be high performing website.

I don't have much experience in this i just thought I would buy domain names just in case I wanted to create a ecommerce website and it went on from there.

*Any help would me appreciated such as where its best to sell domains and how to make money of them.

Thanks
Sam
