Sexuality/Romantic headcanons for Soundwave? I personally headcanon him as asexual spectrum and demi/grayromantic, and I was curious to see how our headcanons compared.

That’s pretty close to mine, actually, especially the romance bit. 

As for sexuality, I feel like he’s somewhere on the ace spectrum, but it’s a slightly odd portion. Like- he doesn’t tend to be sexually attracted to people, period, /but/ he can get himself a bit worked up thinking about what he could do with someone, and he’s open to interface with someone he trusts. There’s just little to no physical interest without his thoughts about the potential to start it off.
