What is the dosage of diflucan (fluconazole) for a male yeast infection?

I got a yeast infection and didn't know it until we had already had unprotected sex so he got it... he went to the doctor and got tested and it was negative... his doctor is the shady kind because he doesn't have insurance and cannot afford medical treatment otherwise... i know he has one because he keeps giving it back to me and it goes away with the yeast infection treatment at the drug store... we can get the medication online without a prescription and its not too expensive but i cant find the dosage... some places say to just take one 150mg pill and it will go away and that has to be bull because when i first went to the doctor i had to take it for like two weeks and i was wondering if the dosage is the same.. please help i am so tired of this... he doesn't have the rash or anything that some men have but every time we have unprotected sex i get one... i read that there are things in his penis that kill the bacteria so that when he gets swabbed the bacteria doesn't show up and this is driving us both crazy please please help asap
