Was I exposed, could I have been infected?

I found out I might've been exposed to hepatitis c, though i certainly
hope not. I was at my buddies last week and we went in the jacuzzi,
little did I know that earlier in the day he and his girlfriend had
been in there and she gave him a blowjob in the tub (didn't swallow
(gross now that it's in the tub)) and my buddy may or may not have hep
c. He had it at one time becase he told me once he has antibodies but
his viral count indetectible and he's had it since the 80's (also has
no liver damage or symptoms - which is great, he's such a good friend
I'm glad it hasn't been a problem for him). Anyway I've done some
research on it and I know that the sexual transmission rate is
extremely low estimated at .03% in some studies to 2.5% in others, but
it's basically impossible to spread sexually almost, unless you try to.

Anyway, I spent about an hour soaking in their tub before anyone knew i
was there and told me to get out. I submersed a couple times and had
some scratches that were scabbed over but i'd had them for a week or so
prior to getting in the tub so they were heavily scabbed.

I'm a bit concerned I may have contracted it, anybody got any idea what
the risk is here? Sure would appreciate some info on this.

**I posted this on another board and had conflicting responses, one
person said that the chances of infection were zero to none, and
another person just simply said it was easy to answer and that i should
go get tested... any input on this would be helpful.
