I guess so. I've just never had a male take this long to figure it out. Every other male I've had would be locked up within 24 hrs, even the young breeders.
Usually this guy, prior to this lock, would "try" for a couple of days and then give up and just go curl up. Same thing this past weekend, and the night I meant to remove him he was curled up not trying anymore. Guess he needed a breather after so much effort with no success.
So long as he's breeding I'm a happy camper - hopefully this pair will give me the BEL I've been trying to make for the past two years. Third year's a charm (hopefully!).
