What is precum fluid? can men feel it?

See answer: Precum (pre-ejaculatory fluid) is a clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal not associated with ejaculation. It arises from Cowper's glands located below the prostate, whereas sperm/semen arise from the testis, prostate, and seminal vesicles. Precum may contain viable sperm from prior ejaculations and men cannot usually "feel it".

Here are some ...: The precum fluid is secreted from bulbourethral glands - in men as Cowper's & in women as Batholin's glands - upon sexual arousal for alkalizing & making male urethra as friendly as possible for sperms to shoot through with semen for insemination and for lubricating vaginal introitus for easing vaginal penetration. Now, we appreciate how the wonder God or Nature creates for us. Men don't feel it.
