Need a more detailed explanation of type of stabbing:

laceration -> penis (S31.21) with foreign body (S31.22)
puncture -> pubic region (S31.139) with foreign body (S11.24)
puncture -> penis (S31.23) with foreign body (S31.24)
puncture -> perineum* male (S31.139) with foreign body (S31.149)

* perineum is the medical term for the area in front of the anus extending to the scrotum in the male or fourchette** in case of female
** fourchette is the medical term for the fold of skin that forms the posterior flower-like thingie ... and if you stab that, code is (S31.44)

... no wonder you need 2 years of community college to work with this stuff.
