Is it ok to masturbate or have sexual intercourse daily or is it bad for health? do this affect my prostate ? or not?

It's ok: The only limits here tend to be religion based. Sometimes men will find it is easier to urinate when they're more sexually active (alone or otherwise), but probably wouldn't be something you'd notice until you were a bit older. I am not aware of any health dangers of daily activity...

Ok: There are no adverse health effects to daily ejaculations.
