We can name men's bits.
Yes we that is because 'penis and testicles' is slightly easier to grasp (so to speak!) Than vagina, vulva, pudenda, mound of Venus, inner labia, outer labia and so on.
And even with men there is confusion when people say 'testicles' when what they actual mean is scrotum.
Honestly, MN is the only place in the entire universe where this is an issue!
