I hate to bring this up again, but I can't find anywhere how old a snake needs to be before you can reasonably guess the sex by the shape of the tail. It's my understanding that it's not the least accurate unless the snake is sexually mature, is that correct? But then I read posts where snakes less than 1 year old attempt mating soooooo . . . that leaves me wondering if I should be concerned by what I am seeing. 3 of my snakes were probed prior to purchase, and 1 was popped, so you'd think I'd be pretty sure on the sex, but every time I look at my male's tails they look short and to me my female's look really long. I have thought it is interesting that I see that with all 4 of my babies . . . perhaps I am just scrutinizing their tails too much?!?
Still haven't worked up the guts to apply enough pressure to pop them, I am seriously considering breaking down and getting some probes. If you all think that at their ages (they are all 2004's ranging in length from 15" to 18") you could tell by their tails I'd be glad to post some pics, just to see what you all think.
