As he said, he didn't ejaculated near my viginal area
Unless he ejactulates inside your vagina, you have no reason to worry. NOT NEAR OR AROUND, ONLY INSIDE. There is no conception unless the sperm can travel through the Fallopian tubes which are waaay past the vagina opening.
You shouldnt worry , But if he ejaculated close to your vagina you shouldnt panic but atleast take a pregnancy test to make sure better safe then sorry BEST OF LUCK
So shouldn't worry at all?
