Cum Blockage is a process in which one has an orgasm and ejaculation, but it is still forcibly blocked by toys or hands (or by congealed, solid ejaculate), making it impossible to ejaculate or delay ejaculation, Sometimes when using sex toys, accidental ejaculation causes semen to be blocked by sex toys. If the blockage causes cum to backflow into the bladder specifically, this is also retrograde ejaculation.
