Thank you for your question, you do not worry about this problem, sexual urge and lowering of libido may be due to a psychosocial or an organic problem. I like to tell you that, you have to check up with a physician to find out if it is because of any depression, thyroid issues, or having premenopausal and many other situations lead to the lowering of libido. You have to check your sexual life to find out the reason and also your home situation and relationship of yours. Youshould see a doctor personally and find out more details about this matter. It is not possible that a nerve could damage, during the time of your second deliver. The important thing is that it does not affect you in years later and it is impossible.I think I have answered your questions well. I wish you all the best and hope for the good, Thank you.
