HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions; therefore, it does not spread or maintain infectiousness outside its host.
You're not going to get HIV from getting semen into a cut.
The cut which is enough for hiv transmission must be VERY DEEP AND MUST ACTIVELY BLEEDING and that kind of cut would put you in emergency room for STICHES .
