Vagina, penis, testicles, genitals, reproductive organs, breasts, buttocks, private parts. (which is a fitting name for these parts, as they tend to jibble.) Can be used to describe one particular private part.
I was bored at church, and sermon hadn't even started yet, but the brunette sitting next to me had exquisite jibblets. Needless to say, it wasn't completely pointless that I went in the first place.
