Can a big penis effect vaginal sores?
Answers: A large penis could mete out pain or soreness to a vagina
as you would expect. actually ANY penis can lead to vaginal soreness, say if there's not ample lube or if it's rough... but a larger one is more likely to mete out pain. yes if your vagina is impossible to having something of substancial size inside of it than yes unsurprisingly it could cause sores and a great deal of pain however not ever time you hold intercourse with this man, the affliction of it will go away after the first few times.
Good luck :)
