Meet Stephen Lexi, too high experienced astronauts assigned on a three year space expedition.

After months of isolation in extremely close quarters and with no privacy, the inevitable happens.

The first sex experiment in space takes place.

Being weightless in space inspires Stephen Lexi to try new creative positions.

However, physics immediately takes over on they struggle to stick together.

When Steve gives Lexi the slightest push, Lexi is sent floating in the opposite direction.

Fortunately, Steve is prepared with elastic bands.

He straps himself on Lexi to the shuttle on to each other.

The next discovery they encounter is their lack of blood flow in zero gravity, since in space of blood rises to the head and chest, Stephen Lexi find it rather difficult to get aroused below the belt.

It also doesn't help that well in space.

All men face decreased testosterone levels that lowers their libido.

So even with all his excitement, Steve struggles to maintain a full erection.

Lexi also learns about space shrinkage as she sees that certain body parts on Steve appear smaller.

This is due to lower blood pressure when Stephen Mexican finally gets, um astronaut on astronaut action.

Things get abnormally hotter and sweatier than usual.

Their bodies have no natural conviction to carry away the heat.

So as they continue to perspire, they create pools of moisture that will separate and spread with every move.

During physical activities in space, the astronauts get exhausted quickly due to microgravity.

Their heart doesn't have to pump.

Blood is vigorously throughout the body like it does on Earth.

This makes Steve and Lexus hearts shrink over time, making the rest of their muscles weaker, which is why they're winded and fatigue.

The last and ultimate challenges to conceive.

However, high levels of radiation in space could cause cell D formation and mutation in the bone structure of a fetus.

Stephen Lexie have not gone all the way just yet, but they are not giving up on this mission.

They plan to avoid the acrobatics on conserve energy with the help of special straps on the fun choreography.

It's only a matter of time before they succeed.

Sex in space may be more complicated than imagined, but it's definitely quite a workout on vital for future space exploration on the sake of mankind.
