While hep c is not specifically considered to be an STD for those who who engage in rough sexual practices or have multiple sexual partners are at an increased risk of contracting hep c.
Hep c must enter the blood stream to be transmitted. The most common means of transmission is through the sharing of IV drug needles. If your wounds were open fresh wet weeping wounds there could be a risk of transmission. You said you shaved two days prior so you should not have open wounds from shaving two days ago.
With that being said I would be more concerned about the rough sex with random partners in general than the two day old shaving.
Your risk is because of the rough sex regardless of your shaving status.
For other blood borne illnesses you should ask in the related forum.
