do people have sex during periods ,some says that it afects mens health?

Ive tried it and it was fine, bit messy but if you dont mind that, some women love it when they are "on" and it hasnt affected my health.

yes it affect with deceases

It does NOT affect mens health providing they are using protection anyway against STDs but periods make NOOOOO difference, except they are messy!

Period sex... hmmm well it doesn't affect a man's health unless you have an STD which by the way would be a concern even if you were not on your period. It is messier, but there is nothing wrong with it, if the guy doesn't mind, it's just blood, and if he's not worried that you have an STD and he shouldn't be because most chicks' I know don't have sex for the first time while on their period. Then I wouldn't worry about it.

A LOT of ppl do it! and my man is still alive....

yeah in the shower show that it doesn't get messy
