My wife is no longer very interested in sex, and we haven't had intercourse for a few years. I take saw palmetto for my swollen prostate gland, but am wondering how Taoist practices may help. The Tao of Loving speaks of "retaining the seed," but does this refer to the semen from the testicles or to the fluid from the prostate? I ask because if I do the practices and let the fluid build-up, it tends to increase the swelling. Since I don't have intercourse, how can I improve this situation?
