NOT AT ALL! Even old married guys, like MY husband, who have a willing partner available masturbate. It's perfectly normal. You may eventually slow down from 2-4 times a day to 2-4 times a week, but at 16 your "trouser trout" is insatiable. Indulge to your hearts content.
When you ARE with a partner, please, ALWAYS use a condom!

I am still a virgin but do everything else with girls, i dont want to have sex until im married. But sometimes when i masturbate i feel like im doing to much, i hear it can cause ED later in life and some disfunctions. Do you know if thats true or not?
