2010 boa male or female without probing

[Scott17]

Hi I have a 2010 7yr old boa roughly about 7ft if not bigger lately I've been wondering if it's male or female I read around the net about spur size but I can't seem to see any on my snake and tail size I'd say it's short but without something to compare with I'm not sure so ye I'm here to ask for advise and see what you guys think the link is a picture of it it's it deep shed so don't want to bother it to much
