It seems that when I masturbate, I will produce very little pre-cum. Yet I clearly remember that the last time I had anal intercourse... When the guy penetrated me, I seemed to be leaking more than I would have thought myself capable of. I was honestly astounded of myself to have such pre-cum. Not that I was oozing by the gallon (if anyone does, I'd consider medical help ), but I did have pre-cum, which is a plus.
