Since losing 41 pounds, (about 18.5 kg), all of my pants are large enough on me that I don't need to pack and even if I do, it isn't visible. It has certainly helped, since I always worried that I had a perma-hard on look walking around. Especially since teenage girls would look at me and giggle (granted, it could have been any number of other things they were giggling and blushing at). My packer is the small peecock, so it was never particularly firm. At this point though, I'm not sure I will go back to packing until I get a better one. I was thinking about a 3.5". Granted, from the time I spent covertly looking at men's crotches for just how visible it was, I rarely saw anything noticible in the states. Here all the young guys wear cups to give them elephant bulge, which is not something I am in the market for.

Now that I am a little older, I realize my first packer looked like that - a giant snake curled up in my underwear.
I will say that I think the husband always found it funny to watch me adjust my crotch a million times before leaving the house, and the one time I had to adjust in public, he told me unlocked a man-chievement. Always good to try and find something fun about socially awkward situations.
