Even though you have someone close to probe for you now, one method that is rarely mentioned but I personally think is pretty darn accurate is the ventral scale count. It's a viable option for those that don't have access to someone that can probe, nor feels comfortable doing it themselves. To have the easiest time of it you do need to wait for a complete shed as most snakes don't want to sit still long enough, upside down, for you to count . . .
You count the ventral scales from the chin to the vent, then the scales from the vent to the tail tip. Subtract the tail count from the chin to vent count. If the difference is greater than 154, it's more likely a female. Less than 154, more likely a male. Of course the closer to 154 either way, the greater the chance of it being inaccurate. FWIW, of the 40+ corns I have counted in my collection there's only been 2 that didn't 'count' right. (One is a snake which I received second hand that has a stubby tail from incomplete sheddings prior to me owning him.) Lastly, the tail scales are 'split' in pairs, side by side, and you count each pair as one.
From the pictures, I would also 'guess' female.
