I've been wearing trunks for years since I was a teenager but recently bought a few pairs of CK briefs. Anyway I've noticed that the days I wear the briefs, my dick is noticeably harder at the end of the day when it comes to some action than when I wear my trunks. Why is this? Anyone else experience this? The only explanation I can think of is I can always feel my cock when I'm walking about in trunks whereas when I'm wearing briefs I can't - it keeps it all together so maybe there's less wear and tear on my dick if you like during the day so it gets harder?
