Obviously if a guy does anything sexual with another guy he’s bi. That’s literally the definition of bi. Literally everyone in the videos in this thread are at least bisexual. The meaning behind “straight guys doing not so straight things” is about guys who live a straight lifestyle, i.e. have a wife, girlfriend, or don’t identify as straight or live a predominantly heteronormative life. Obviously if someone is exclusively straight, they wouldn’t be fucking a dude. At the end of the day tho, you have people basically looking up porn for you without any effort on your part. Just enjoy and jerk off. No need to shit on anyone for posting what gets their dick hard.
Happy jerking
