Sometimes I do.....sometimes I don't. I was always a skinny kid growing up, and when I had that growth spurt to 6'1" my soph yr in HS it got worse. Felt like a lanky nerd! Finally got my weight up to 160 pounds and it's been that way for the last 38 years. I'm thin, but in shape, and my chest still sticks out farther than my stomach. Since college I've been in four LTRs, and I remember the first time I was naked with each I didn't think twice about it. I loved being naked with them, in and out of bed. Now having been with the Mrs for 20+ years I don't have a problem being shirtless or naked. Sometimes the softening of my mid section has me thinking I should put a shirt on, but it's summer in Florida and I do a lot of yard work, and I say heck with it.
