Welcome to the board! I am an older guy, you are in good company. Keep in mind, when we were young most guys wore Speedos so we just keep wearing them. I can wear briefer styles now, ordered from around the world.
To post pictures, I go to
http://www.resize-photos.com/ upload the photo, select 800 pixels and move the slider to 50%. I download and save the photo to use here, you can see my shots in other postings here.
