I've had several girl crushes over the years, some of them friendly aquaintainces who found me flattering (I've never hidden it) and some random strangers I'd eye in the bus
When I'm hypomanic girls are super attractive, I've never acted on this sudden appreciation of the female form, but it did have me questioning my sexuality at one stage. That's when I discovered it was purely episodic and stopped paying it any mind.

It has never affected my relationships though, bf and I share the same celeb crush
