How so?
We see sexuality used in a lot of games. Inquisition and the Witcher use it liberally to convey either relationships or just sex and gender roles. Sometimes it's good, sometimes its too much.

Sexuality is not the always bad Thing.
Designing a Race solely because they should "embody Sexuality" is always bad.
Which is exactly what happened with the Asari. They were designed to be the hot Alien Chicks. Their whole Lore reflects it. And that is bad.
Look to the Quarians, when you want to see it done right(-ish). They are absolutely attractive, yet still not designed to "be the hot Aliens".
I stand by my Point. Get rid of the Aliens that were just designed to be hot. Especially if they don't make Sense, like the Asari and their Bullshit Reproduction System (and yes, I am aware that there are species who do Parthogenesis. No, they still don't especially **** others Species.)
