I'm still not too sure. I don't really see bulges and I do see pores, but sometimes females have slight pits where the pores are. Sometimes you can push on the place where the bulges should be and the hemipenis will pop out. That's pretty definitive!
Looks like a female to me. Like acpart said the buldge isn't very pronounced and the pores aren't hardly noticeable. I have a 5 month old male and the bulge behind his tail is fairly larger than what I see in your pictures. Just in case I am wrong, I'd keep an eye on the pores and see if they get any darker. Every Leo is different but it looks like a female IMO If you want to know asap, I'd take it to a professional to have the popping done so that you don't risk hurting your leo if you're unsure how to do it yourself. Hope that helps.
