i work construction and in the winter, let me tell you, if it's -10* and you are cold the old balls & cock tuck into your body for warmth. it amazes my wife, that my cock can go from about 1 1/2" to over 7" in a few minutes when I get home and snuggle up for our late afternoon nap/ fuck session.
I have always been a grower, not a shower. my wife's gf, walked in on me snoozing after laying pipe to the wife. I was full, large, limp, totally flaccid. the gf later told me she saw me, "my god, you ARE big, and THICK. you are skinny, and never show much bulge. the gals always wondered what your wife was getting from you. I'm jealous."
