The Women's Motorcycle Contingent looked very leathergay, but my "straightdar" went off at a few of the women.

Above all, be very careful about whom you tell that you are straight. Try and find other straight people, but it will be hard because everyone will be trying to act gay. Use your "straightdar."

<G> It is 'gaydar' -- and mine has never been wrong so far... My 'straightdar' HAS been wrong once -- I mistook a lesbian for a straight girl (we became best of friends after that).

My gaydar's terrible, but my straightdar is pretty good.
2008, Robin Sawyer, Sexpertise: Real Answers to Real Questions About Sex, Simon Spotlight Entertainment (2008), →ISBN, page 177:
Gay or straight, we've all made incorrect assumptions about someone's sexual orientation, so the likelihood of “gaydar” or even “straightdar” as a meaningful idea is unlikely.
2013, Tom Ryan, Tag Along, Orca Books Publishers (2013), →ISBN, unnumbered page:
I told you I had great straightdar. I'm great at helping girls figure out boys and giving fashion tips and stuff. In case you haven't noticed, I'm the only out gay student at Granite Ridge High School.
