Can viruses be gender specific?

I have noticed lately that around the place that I live that a stomach virus is going around. While both males and females can get the virus, I have noticed that the only ones being severly affected are males.

Question: can a natural virus be gender specific or can it affect one gender more than it affects the other?

I am not sure so I am asking everyone here what they know.

Well some STD's only show simitems in men/woman but apart from that i have not heared of any. Why would a virus evolve that limited its victems. But there should be no problem in creating one some day. Dose any one remeber a movie about this very thing.

we are all creature of the almighty supreme being & have everything in equal i think if in somewhere there will be a virus it will affect all , coz it's the same functional system both for males & females good luck.
