Hello
Thanks for writing to us t DoctorSpring with your health concern.
Masturbation is a healthy valid outlet for your sexual desires.
There is no side effect from masturbation daily, even multiple times.
What you should ensure is that it does not become an obsession or interfere with your daily life and routine activities.
Otherwise, there is no physical danger from masturbation frequently.
All the best
Please feel free to discuss further
Thankyou
