Your prophet had sex with his 9 wives in one night and had shower only once..you call this hygenic? Sex disease can develop from having multiple partners without protection..

There is no evidence he had sex with 9 wives in one single night.
ISLAM IS THE ONLY RELIGION ENCOURAGE followers to bath after sexual activity.Islam also forbids followers to pray without purifying them self.Muslim has to pray five times. Muslim has to bath before each prayer time.


If a man has multiple wives , He has no chance to get STD as those women will sleep with the same man only.
If a man sleeps with multiple women who also have multiple sexual partners, there is a high chance to get STD.
