"Fuck" is sexy.

fuck lol

It depends, for me anyway, on the context of the rest of the sentence or intent behind it. If I'm talking to customers, or writing reviews, or blogging "sex" is the word of the day.

IF, I'm getting randy with the honey fuck is hot, or hot as fuck.

If I stub my toe fuck is the word. And WTF?!?!?! just doesn't have the same ring as WTS?!?!?!

Then you have; Fuck me?!
and of course; Sex me?

I love the diversity of the fabulous F word! But in terms of professionalism, the word sex works perFectly well also.

fuck...or makin love xD

Both are the same depending on context, but "fuck" in the sexual sense makes it out of my mouth about twice as much as "sex" does.
