Intimidated

So a few times in the past, I've ended up having to defend myself in HR situations due to making female co-workers feel intimidated. Now obviously my view of the situation is biased and incomplete, but I maintain that it can be difficult to avoid simply because if I disagree with a co-worker and state this, my size and volume automatically make me seem scarier, even if I try to not be. I obviously try every day to work to prevent this, but there's a floor here.

And unrelated, I tend to not be willing to make first moves romantically.
