this is a common question. in general regular use of any body part the way it was designed is a good idea. infrequent ejaculation can result in a build up of fluid and pressure. it also allows fluid to remain static and so can increase chances for infection as men get older. there are many experts that think that regular ejaculation actually decreases risks for prostate cancers. so yes regular ejaculation is probably for most a good idea.
is there a relationship between the frequency of sex and a healthy prostate?
