This thread is thoroughly interesting.
I wouldn't say my wife is "obsessed" with my dick, but two things come to mind on her opinion about it.
The first time she actually saw my hard dick, all that came out was a simple, almost silent "wow". Since I'm a grower, I guess she wasn't expecting it to be the size it is while hard. I'm telling you, she didn't let out a loud "oh, my god, you're so fucking huuuuuuuge", but that hushed "wow" and the twinkle in her eye were a huge stroke to my ego.
The other thing is she's told me time and time again that I have a beautiful dick. I always find it funny to hear it, because I never thought of penises as particularly aesthetic parts of the body, but hey, what do I know about it.

And on the clothing department, she won't ask me directly to wear any specific revealing type of clothes, but she does like it when my bulge is more noticeable and, not only that, she does love to tease me when I'm about to leave the house and have me go outsite with a semi or a boner

Now, imagine that when I'm wearing grey sweatpants... She does love giving me a hard time, that's for sure.
