My sex drive is inextricably linked to my overall physical state, it seems. Back when I biked or walked everywhere I went, I had a high sex drive. In the past several years, I have walked relatively little and biked far less. I also have not worked out all that much; exercise is much easier for me to do when it is a part of what I do, not a separate task. In the past few years, as I have stayed fairly inactive overall, my sex drive has also decreased. Recently, I took up gardening and noticed that I feel good and feel horny again.
