Masturbation timings and premature ejaculation has no correlation and isn't connected. I observe that you are tensed about your performance and are insecure about the same. Develop confidence and take it easy and stop the unnecessary over assessment of yourself . Allow yourself to learn how to be intimate and enjoy the same instead of focusing on performance.
Next Steps
