After reading some of the other posts, I actually took a look through my underwear drawer. Guess what, there were actually two pair of men's briefs in there. I've been with my b.f. for 2.5 years and have never cheated on ANY boyfriend. They just happened to be in there and I totally forgot about them (admittedly, I have a ton of underwear and and they were at the bottom of the pile and not in plain site, but they will be in the trash today). I guess the fact that the panties were in an open drawer is a bit different but I'm just not sure that this guy is a cheater....maybe he wants to create jealousy because he himself is insecure? I still say to wait to talk to the guy before freaking out. I sure would want the benefit of the doubt.
