Hi! i was wondering what the risk would be for hiv if hiv positive person cums and that seman you used to masterbate with?

Any skin breaks on hand or penis maybe, Get checked in STD clinic, Good luck.

Little or no risk of infection. HIV has never been known to be transmitted by hand-genital contact, even when an infected person's genital fluids are used for lubrication. That doesn't prove it can't happen, but it does mean the chance of infection is exceedingly low. Testing isn't necessary after such an exposure.

Doing this knowing the person was positive is taking chances. So the risks are there depending on the condition of the surface of your hand and penis.Pl try to avoid such things
