Given my line of work (escort), I am often quite open when it comes to sexual activity. Because of my laid-back outlook, I've never had a problem giving a man friend a casual bj if he's been having a poor day. As we sit there, he will occasionally make a joke or flirtatious remark about hooking up, and I will simply grin and respond, "Ok!" Shock always has a great look. Obviously, this wouldn't work for everyone, but if all parties are emotionally capable, it improves everyone's quality of life.
If anything, I think the word "whore" is a compliment, so maybe don't heed my counsel.
