Someone who has a fragile heterosexuality believes that hanging around, talking, and or experiencing anything that is gay would convert them/associate them with being gay. Hence the name fragile heterosexuality, because it's easy to break.

For Example:
Someone who would have a strong heterosexuality would be able to indulge in gay jokes, gay media, and or experience a gay moment without fear of becoming gay, because they know they are straight. Someone who has fragile heterosexuality would avoid the situation as a whole or be homophobic when confronted in fear of that conversion.

A common trend with people with fragile heterosexuality is that they think every gay person is out to get them. That any gay person they meet will have a crush on them.

This begs the question; are they really misinformed/raised that way, or are they in the closet.
Example1:
Alex: Hey want to watch that show called queer eye, it's just a bunch of dudes helping people out through tough times.
John: Nah I don't watch that kind of stuff.
Alex: Like heartfelt life turn arounds and stuff?
John: no, not that, just the name, and those people you know. I don't watch that stuff
Alex: How fragile can someone's Hetero sexuality be.

Example2:
Rory: Yo bro we can get some extra community hours by helping out at the gay veterans event.
Lee: No dude, I'm not going there to be associated with that crowd. Let's do something else.
Rory: What? Is your heterosexuality fragile?

Example3:
Liz: Hey do you want to talk about it, I didn't mean to bump you.
Sarah: What are you going to do, make out with me?
Liz: No, I'm just trying to help. What a fragile heterosexuality.
