All information below is for the MTL, and uses the MTL names. The official 072 version fixed the missing naked menu option.

Original post:
I can't unlock the menu option either, for some reason. Even with the former number 1 giving it to me. [EDIT: This was a bug in the MTL, documented later in the thread, 072 works fine]
Here's a very quick of the areas/girls from my notes:

Notes:
"Repeat" means "come back tomorrow at the same time".
Hours are not all strict, most of them are actually ranges. Check the girl's entry in the menu.
To get points, and raise your rank, come in/on the girls you come across at least once per sex session. I don't know if coming more than once in the same sex session wil increase it further.
Impregnation is a fixed 25% chance after coming in/on a girl, evaluated once at tne end of the sex session (so coming multiple times won't do anything).
Pregnancy doesn't actually do anything beyond increasing the daily money you get, and increasing a counter in the girl menu.
