Something similar happened to me, but my ex insisted it was mine (I wore an XS at the time and it was a M). I seriously understand that sinking, heartbreaking feeling. I'm sorry, OP.

This may be a good time to get tested.

In college it seemed like almost every time I or my roommates ended up with a girl staying overnight, the women would leave their underwear in the bed or on the floor or someplace they'd be found later. Dozens of them, over the years. I cannot imagine that they all just forgot their panties. Is it territory marking or something like that? Is it giving a reason for calling them later without actually saying "hey call me later"? Maybe it's a trophy awarded for doing well in the sack? Inquiring minds want to know!

i dont get it how ppl forgets their undies after sex like ******* how?

I mean, I can't say whether or not he told the truth but it isn't out of the realm of possibility as some have posted nor as creepy as they are saying.

Well, it does say your in Alabama..

If his name is Oedipus you might wanna give him the benefit of the doubt.

His thong got tied ?

Since the author lives in Alabama the panties could be his cousin's.

You're from Alabama, probably his sisters or cousins or something
