Alien Trisexual Hermaphrodie 2017-01-28

I'm curious if the gender options we have are universal. So here's a play on an old joke - a try-sexual. I imagine having 3 penises and 3 vaginae could make a species with interesting relationship and sexual possibilities, though the mechanics might be challenging. If they worked them out it could mean 9 of these aliens all have sex together. My imagination worked out how self pleasure and 3 having sex could do it. So would they too have a special rating for intimacy with only two of them having sex but all three receiving and giving to each other. Babylon 5 was a head of me with this one as the Centauri had multiple sex organs though they were not hermaphrodite.
