Not to be awkward, but it looks like Jo Rivera and Kailyn Lowry's one-night stand on Teen Mom 2 was far from clean — despite the fact that they did it in the shower.
On Dr. Drew's Teen Mom 2 reunion check-up, it's revealed that Jo and Kailyn had unprotected sex, and then Kailyn came down with an STD — which she, in turn, exposed to her then-boyfriend, Jordan!
The two of them were tested and medicated, which leaves Jo as the source.
"Wait, did you just blame me for giving you STDs?" Jo asked Kailyn.
"I mean, you told me you were with six people, and I specifically went and got tested because I cheated on Jordan with you," Kailyn responded defensively.
Sigh, we'll never know who infected whom, but we've learned one important lesson: Always get tested, and always use protection!
