cuts start healing from the inside out almost immediately. a one day old cut is not a sufficient entry into the bloodstream.
you had NOOOOOOOOOOO risk.
So if he doesn't agree to test. So may I have any risk as my story?
Of course yes, he told me in the past he had sex with just 3 people with condom all the time. However, I still doubt him though he had well knowledge about STD's and HIV.
Doesn't matter. It is not a risk.
Why not talk to your boyfriend about STD's and HIV?
But his sperm on my hand which is with a tiny cut near my nail. This cut was one day ago and didn't bleed, but it still make me worry.
You never had an exposure. HIV is not transmitted by masturbation.
