Yeah, probably wouldn't have hurt to have a fecal done. It would help to be able to actually see the behavior. My males are very active when they want to breed however I have never seen them do any displays without the female being around. My females on the other hand will often put their tails up and, forgive me, squirt a little even without the male being in the same cage.
The oddest thing I have ever seen a reptile do was when my daughter's tortoise fell in love with his water bowl. I kept hearing chirping and went to see what it was. He had "mounted" the water bowl and was chirping. I didn't even know they vocalized at all.
