Simple? I'm no Puritan, but I'm hesitant about clicking a button that starts with the word "sex". I'm not used to professional high-quality services resorting to ... well, it's not vulgarity, but sex is sort of a traditionally taboo topic. So in spite of how good your product my be, here I am thinking it's more likely to suck because you broke this unspoken rule. But maybe that's just me.
The words are simple, but the choice to include the risky language is not 'simple', in that it's risky/innovative/uncomfortable/attention-grabbing (depending on viewer's perception). I guess a good word is 'unusual'.
