Good point!

In fairness, it is (by design, I think) really hard to tell when Garak is trying to bed someone or just has a soft spot for them.

But yeah, there's plenty of evidence Garak could be bi.

I don't think it's erasure to guess when it's such a mysterious character though, right?

We can ultimately only speculate because Garak guards his secrets so closely to protect his career as a... plain simple tailor.
