I've always worn tight underwear - boxers are uncomfortable.
When we started trying I was hoping / expecting it would take a while, if ever (I wasn't quite on board !).
As far as we can tell, it took two days. Tight underwear doesn't do much damage...
Heh, same here. We actually thought it would take at least 6 months to bear fruit (so to speak), so we were prepared for a long haul. This was more due to her problems, but I also wear briefs, so we thought it might take a while.
Yeah, it took maybe a couple weeks.
