Obviously I would say my cock so aside from that... my eyes (light blue), my hair (blond), my smile (nice teeth!), my feet (they're big at size 12 but I think they are very well formed and perfectly blue-white with nice nails and no hair), my skin - I am white and very pale (you can see my veins through my skin) and my skin is very clear... almost blue and quite translucent; my mates have said I look DEAD but I like it. I also naturally have very little body hair. Aside from my head, all I have is a sprinkle of fine, white-blond wisps under my arms, around my cock and a dash on my lower legs. That's all! Virtually no shaving required!
Least Favourite
I would say the fact that I am so fucking thin. My waist is 29-30 inches and I am well over 6 feet tall; too thin. My thighs are especially thin and though this makes my cock look freakishly large, I would like them to be more muscular. I also wish I had an ARSE! It is so flat and bony. My wife says "God Divides" - he gave me a huge cock and gave me NO ARSE...
And sometimes, I would say my cock is my least favourite part of my body. Finding underwear/trousers/Speedos/shorts/lycra shorts/jeans/jockstraps THAT FIT or don't make me look like a perv is a challenge and it does get to be a drag. Getting hard in a public place when you don't want to (this happens to me a lot), especially when you are wearing something particularly revealing. Also when blokes or ladies just STARE at your crotch when your mind is not on sex... office, work, etc., that can be boring.
But I say that with reserve because other times, when I am feeling a bit frisky or need an ego boost... There is nothing that boosts my ego more than to put on a very revealing pair of trousers/shorts/lycra shorts/jeans/sweats without any underwear and go out for the day or evening. I love to get hard "accidentally" and watch people stare nervously (or lustfully!) - it's a great high!
