Welcome to the forum, clementine.
I've moved your post. Since Abuse is specifically for abusive issues. And it seems like you're interested more in the non abusive aspect of it.
Yes, I've read stories from people describing GSA. It's clearly a thing that happens to some people. Like you say, a broad term of attraction.
If you don't mind me asking. Why are you curious about it? Is it something you or a friend / family member is experiencing?
