###Human: I have no desire for sex. Is it because I use tobacco? ###Assistant: Hi. Kindly quit tobacco immediately. Tobacco usage is one of the causes for sexual dysfunction. You can take capsule Nano-Leo two capsules in the morning and night after food for three months, which is slow acting. After a month, let me know how you feel. If it is not effective after three months, you have to undergo investigations. So, get back to a sexologist online after a month -->
