Ok now he's starting to look like a male. The second to last picture shows jowl development and I can see what look like bbs in the tail picture

Yes, but "he" should have signs of even slight jowels growth by now. Especially if "he" is around 3' long.

Absolutely no sign on jowels and girls are smaller typically

Looks like a she BTW. Congrats on being able to keep her!!
