This is how I contracted hep c from my wife who got it from the hospital through a blood transfusion.I wished I had used a condom then.I am on my 2nd marriage and I always use a condom now and I get her tested yearly.Hep c is tough to get rid of.I'm on my 2nd treatment in the last 18 months.
That is most assuredly not safe sex unless you used a condom. That is unsafe sex to most people and to be sure you should have him tested because none of us can tell you 100% either way.
