My significant other and I are looking to find out why he secretes a fluid much like sweat at the base of his spine only when he is aroused. We are wondering what it may consist of and why only when he is aroused? He has only noticed it in the past 10 years or so and he is currently in his later 60 s and in AMAZING health.
Hello, He needs to be examined by a doctor for the source of this fluid. A search has to be made for any small discharging spot (called sinus in medical terminology). If discharge is not from a spot, and it is from a diffuse area then it is likely to be sweat as you are suspecting. The sweat glands are distributed all over the skin and density of these glands vary in different parts of body and in different individuals. It doesn't really point to a specific disease entity and I would consider it as a normal variant. Good luck.
