Hello and welcome to Healthcare Magic. Thanks for your query.
Decrease in libido can be due to various reasons. The most common causes are
hormonal imbalances (like increased
Prolactin), psychological factors like stress, medical conditions like
diabetes, side effects of certain medication, etc.
So, the first thing that you need is a detailed evaluation, in to find out what the exact cause of your low libido is. For this you will have to have certain tests like hormone levels, blood sugar, etc. Based on the results of your tests, your treatment has to be planned accordingly.
There are also certain medication like
Bupropion which can be used to improve the sex drive in persons with low libido. It is also important to reduce stress and
anxiety and follow a healthy lifestyle in order to have a satisfactory libido.
Regarding your question about anal sex, you can use KY jelly - which is a water-based, non-allergic and safe lubricant.
