How can I test if my pet turtle is gay ?

@crotchrot I tried but the male and female got it together and he just stood like a lemon

@TechniCoIorBroccoli maybe he's just not interested in having sex.

@TechniCoIorBroccoli Some species mate for life. Just get one female turtle and see what happens. Don't you have a vet that you take your turtle to? Some species you can tell, others you have to um, "sex" to find out. Birds and reptiles often have a cloaca, a kind of "trap door" where their parts are protected until ready to use. I imagine this would be traumatic to your pet if done.
