Do you guys think astronauts on the space stations have sex with each other?

Honestly, If you REALLY think about it, because plenty of shows/movies have shown it (like ALIEN for example) but I want to know is, does it actually happen, in sex in space possible or do you think they have it, these people who are literally up there for god knows how long who have only a few people to socialize with every single day, I know damn well if I was stuck in space for more than a year or years, I'd get pretty touch deprived and want some action, I'm sure a woman or a guy would want it as well, or maybe they form a romantic relationship and get together you kniow. What do y'all think, (honestly, I think this is perfect for this thread)
