Embarrassing relevant story time: One time in a ballroom dance class I was taking, I paired up with someone, then somehow epically messed up the handhold and accidentally interlocked fingers. She was horrified at the improper hand-holding and avoided me the rest of the semester
One day, me (male) went for a handshake with a pal (also male) and the moment we touched hands someone pushed him towards me, and I grabbed him to he wouldn't fall. The next thing we noticed is that our fingers were interlocked and I swear to god this is the day he won't even fistbump me due fear of the gay.
