Tom Thurlow's "shagatuni.com" encourages members to send each other saucy messages and meet up for no-strings-attached liaisons.
He designed a new website which has been launched to allow university students to meet for casual sex. He claimed that it is being dominated by female students from Oxford.
It allows users to post a Facebook-style profile which explicitly advertises what they are looking for in a sexual partner.
Thurlow, who became well known after setting up a successful second-hand book business at 13, now claims the biggest uptake so far appears to have been from young women studying at Oxford University.
He said that statistics show a whopping 722 woman from Oxford signed up since the site launched in October.
But Oxford's biter rivals Cambridge University prove to be the most prudish - with the lowest amount of members in the whole country, the Daily Mail reported.
"The site is aimed at 18-30s university students, college students and people who may be friends of students. We have seen a real boost from the Oxford students," he said.
"I am not surprised. When I tour the country filming MTV Freshers the Oxford students are always the most wild.
"They are always uptight in the day but by night they were always the craziest. It doesn't surprise me they have the highest proportion of women looking for sex," he added.
The site advertises itself as a space for students to have sex without "the strings attached with dating."
It boasts 26,933 members with 18,400 men and 8,533 women signing up for membership since it went live two months ago.
Sex-crazed students aged 18-30 can create revealing profiles supplying potential suitors with descriptions of themselves and their sexual preferences.
Some of the academic members even include naked self portraits and explicit details of where and how they like to have sex.
