The three some equivalent of an Eiffel Tower consisting of two female participants and one male.

My husband told me that a female and a male were incapable of the act of simultaneously engaging the same female in sexual intercourse and oral sex while the couple high fives above the second female's head/body, known as an Eiffel Tower, arguing that only two males can properly "construct" an Eiffel Tower utilizing their penises as a base for the tower, and the act of a female and male engaging in the same type of high five above a second female is known as Manhattan Bridging.

Manhattan Bridging 

The equivalent of an Eiffel Tower (A threesome with two guys and a girl, where one guy is hitting it from behind, and the other guy is getting a blow job. The guys are high-fiving over the girl to make the eiffel tower shape.) but the threesome involves two girls and one guy. The guy is banging one girl from behind while the same girl simultaneously gives the second girl oral sex and the high five takes place between the guy and the second girl = Manhattan Bridging

I assumed that a girl could take place in an Eiffel Tower during a threesome involving 2 females and one male, but my boyfriend corrected me and informed me that what I was referring to was actually Manhattan Bridging.
