I always had a high libido, but then I went through a period of about 18 months with a medical issue, and came out of it with a significantly lowered libido.

I was planning on telling my doctor about it, I probably need testosterone supplements or something, but I realized that I was getting a lot done without sex constantly intruding on my thoughts. Frankly, it's been liberating.

I had a good run as a young man, with plenty of great memories to peruse. Now I have hobbies.
