You've got a fantastically gorgeous cock!
Looking at the side-by-side shot, the erect head has great proportions and looks like it is rock hard. The pee hole looks like it is gaping open. Very hot! Makes me think of a huge stream of cum blasting out of it. The head looks like it is at a slight angle from the shaft. I love minor asymmetry like that -- it makes a cock unique.
The shaft is straight and I love the subtle veiny-ness. Others have commented on you being a grower. I'm not sure whether the two side-by-side pics are exactly on the same scale, but the transformation from soft to hard must be an exciting thing to witness. I'd line up to see that for sure! Or to experience it go from soft to hard in my mouth.
As one into sharing my wife's cunt with a buddy, I would rate your cock as EXTREMELY wife-worthy.
I would love to see a side shot of your erect cock too.
