i had also tore my frenulum.
i had a tight frenulum, dunno what caused the tear,
i dry jelq really hard, stretch, masturbate hard, so i think it's 'hard'
to tell which action caused it... could be all?
v. similar to what u described... bled at the frenulum.
freaked me out. stopped everything for a few days.
then it bled again when i continued.
it looked like there was a small hole at my frenulum at close examination.
(sometimes it hurts when urinating. i tot it was infection)
sometimes a little bit of the frenulum would peel off.
the tear finally healed after some time (a month or more, cannot remember)
of inactivity, when the 'hole' totally disappeared.
