They have increased levels of parasites because they have a lot of oral sex and as the stats go increaed number of sexual parasites... their sexual activies orientaite greatly around the 'nether end'.

There is a connection to parabens though... turnd male frogs to girl frogs or the other way around...

They dont have the parasites before they engage in the sexual activites that they do... The kind of causal sex we are talking about... complete strangers... hookers... cottaging... so actually hanging out and having sex in toilets.. you are going to get them...
