I didn't lose interest, but it takes two to make a match happen, and I haven't heard anything from my opponent since she didn't appear for our two attempts at meeting last weekend.
I think that part of the trouble has been that people entered with different ideas about what constitutes a sexfight. Some people are only interested in the wrestling part, and trying to control your opponent to make them orgasm, while others like titfighting and tribbing and consider it more of a sexual competition than 'fighting'. I think that for tournaments in the future, it would be better to be very specific about what sort of match is expected, so that people who enjoy the same type of match all enter... Just my two cents.
