Hi Thank you for asking HCM. I have gone through your query. Low libido can be due to physical problems like anemia low level of testosterone or hypothyroidism. So a general check up of his physical well being is necessary. If it is these can correct well with proper management and exercises. It can also be psychological. In such case counselling with psychologist will help you. He can take aphrodisiac foods like seafood prawns, squid, mussels, eggs , meat , drumsticks which all increases libido. Exercise daily also increases testosterone levels mainly muscle building exercises. Dress in front of him Sexy and use perfumes which he likes. Hope this may help you. Let me know if you have any further queries. Thanks
