Thank you for your question. Masturbation is good for your sexial health. It helps to keep up the quality of sperm by flushing the system regularly and making sure that none of the glandular secretions are stagnant. It is protective because you are not exposed to any risk of sexually transmitted infections. It helps psychologically if done alongside pelvic floor exercises because you can learn to delay ejaculation and build a stronger erection. Men who masturbate regularly without feeling guilty are more confident, self aware and have better self esteem than those who do not masturbate Finally, masturbation has no long term detrimental effects on reproductive capacity or sperm quality. I hope this reassures you. Please allow your self to enjoy the experience and practice when you are relaxed and without hurrying.
