Neil deGrasse Tyson is like everyone's second dad who happens to know a lot about science.

But he's still just as embarrassing.

In a video from National Geographic, the scientist explains what it would take to have sex in space. And things get super S&M real fast.

"If you want to sort of get together [and] stay together, you need something to, like, keep you together during all the normal body movements that would characterize having sex in space," Tyson says.

"So yeah, just bring a lot of leather belts to keep things strapped down and you'll be just fine."

Neil gets even more awkward at the end of the video.

Just stop, Science Dad. Just stop.

The news: A game-changing condom that kills almost all sexually transmitted infections, including herpes, HIV and HPV is one step closer to hitting the market. The Australian market, that is.

Ansell, the Australian prophylactic company, will manufacture a condom laced with the antimicrobial VivaGel lubricant. Australia's version of the Food and Drug Administration, the Australian Therapeutic Goods Administration, gave the product a Conformity Assessment Certification, meaning that it could be on the market within months. The gel is proven effective in killing 99.9% of sexually transmitted infections (STIs).
