As well as the above suggestions make sure your persona matches this type of booking- in your blurb say things like I just love no strings sex, I just need a good fucking etc, talk about loving anonymous sex, the thrill of screwing someone you've only known for 2 minutes or 'Sometimes you just need a fast release and not have to have polite conversation'.
I agree if you're not careful you might encourage those who are a bit rough or disrespectful, so rather than be too explicit market yourself as strong, independent, feisty and very sexual as opposed to talking about yourself like a bit of meat, so avoid 'come and fuck my dirty slag holes' type thing!
