to better explain what happens when you massage your prostate, you get prostatic secretions, which is part of what seman is made up of. Pre cum is produced by the cowper's gland and is compltely different, I to drip out huge amounts of juice when I massage my prostate, get fucked etc.... but is not pre cum. is basically seman. Not bad mind you, but want to drip juice when hard and randy, yall know you know men like that, wind blows, cock gets hard, juice drips out.
