when i have sex, getting him in is rather painful at first. after about 30 seconds its not painful anymore though. but about 20 minutes in i start to feel chafy 'in there' and it starts to hurt. then going to the loo afterwards is mega painful. i mean, size-wise, he's on the rather large side...
if it's just light blood, and not much pain, then yes, this is normal. i had it for a couple of days. just wear a pantyliner and it stops.
if it's heavy blood and painful to pee, then if it lasts for over a week then consult your GP.
