After having intercourse with a female who is menstruating, you then proceed to have anal intercourse. After that is finished, the female may flatulance, resulting in a fine red mist, or a "blood fart."

Get the poop fartmug. A fart so thick and eggy, that it smells like it could have only been a female who dropped it. This is mainly due to the estrogen-enriched nature of the scent cloud. (Note: Men are capable (albeit a rarity) of dropping estrogen farts).
I was browsing the internet when Brad dropped an extremely thick estrogen fart that made me question if a woman was in the room.

Get the Estrogen Fartmug. Draconian punishment for the fussy girfriend who keeps complaining about your unavoidabe flatulence, and who keeps escaping when you try to hold her head under the blanket.
A rich fart is released silently into your hand, you expell all air from your lungs then breath in the fart from your closed hand. You now make an amorous approach and breath the fart into her face / mouth as you kiss her. This will cure the problem as she WILL leave you. Failing this you repeat the procedure but first you bite strips of of your fingernails and wedge them between your teeth - an "indirect fart with nails"
