[Mass Effect] Alien genitals. How do they seemingly all fit together?

Im a bit confused as to how it all works. Humans can have sex with Asari and Quarians and Turians and Drell and Prothean.

Prothean! 50,000 years of evolution on opposite sides of the galaxy and still humans can have sex with Protheans. What the hell is up with this?

The genitals of human men don't fit with the genitals of other men. Likewise the genitals of women don't fit with the genitals of other women. That doesn't stop them from having sex. People are creative.
