I broke my back 8 months ago and my menstrual period has not yet returned, is that normal?
Yes, it may take up to one year for your period to resume after the injury.
I am a man with spinal cord injury, is there anything I can do on my own to improve the quality of my sperm?
How often can I use the vibrator?
There are no limitations. Stop if your penis becomes red or if you have a persistent erection.
