Couple things there: Axe is owned by Unilever, who also makes brands like Dove - they might not want the press of "owners of Dove advertise on shock porn sites" or whatever. Axe might be ok with being associated with "two sexy people going at it in a traditional way" type porn, but not "bunch of funny looking people having 'strange' sex" type porn, and discriminating between the two might not be worth their time and effort. Axe is probably bought, at least partly, by moms for their young teenage sons - who might not take kindly to actual sex being that tied to their advertising. Take a look at how they currently advertise - it's sex, but with a goofy/comedic slant. Think the ads with the astronauts - those are legitimately funny.
