How to - mate - the female HUD

Initiate the mating

As soon as a male HUD is close to you the blue sign (Mars) appears on your HUD. Now you can

touch your HUD
select "Open for..."
the name of the HUD owner

During the mating

As soon as the connection has been made, the Mars sign shows filled. At this point the male can ejaculate inside you, using their HUD. You have the following options:

Close from... <--- you can remove the male from your HUD again
Open for... <--- if there are other males around, you can open for them as well, for MMMF fun
Use Condoms <--- if you got condoms you can now apply them

Things you should keep in mind:

The best time to conceive is during ovulation. The writing above your HUD will be in violet then.
A pregnancy test prior to day 25 in a human setup will fail. Also scans with "Physician bag" or other tools prior to that day will fail
