Masturbation and intercourse?
I ask because I heard that masturbation for guys can negatively affect them, so I wonder if that's the case how come the sperm I during the intercourse doesn't have the same negative effects?
Its sperm in both cases so what's the big deal about masturbation?
By the way am 25 years old male and still virgin so my question may sound bit naïve.. just had to ask and know the answer.
