How can Men & Women call themselves ''Straight'' if they have never tried gay sex?

I've had (all-together) 0.8 gay experiences. Unlike most of the angry posters ITT, I once started a gay dare with the OP's intent. all 3 friends had to pop each other's penis into the other's mouths for a second.

No it did not turn me gay. That was 0.2 of it.
