anthropomorphic Lizard question(Nsfw)(18+)(for anatomy and biology purposes only)

If male lizards have a slit to hide their penis, what does it look like when it becomes erect. Like when their penis slowly emerges from their vertical or horizontal slit. the second question is what kind of penis designs and details can be found on the internet.

Depending on the kind of lizard it will be either a smooth pointed cock, generally pre-lubed, or if it’s on a dragon it’ll have a thick knot near the base.

The tag you’re looking for for references is “genital slit”
