'I don't care if you have a same-sex crew of great-grandparents who have never had a flicker of sexual desire in their entire lives. Lock a group of humans into a ship, sail them through space and time, and it won't take long for that deep, ancient need for touch and intimacy to surface.'
This is the first pornsite I've found in years that I'd actually advertise to swarmers. When you first load it up, it looks just like every crappy scam site out there, except that it's real. It's huge, it's updated constantly, there's no spam, no popups, and no bullshit -- and it's completely free. When you sign up through that link above and respond to the confirmation email, I make a bit of loose change.
See what other swarmers have to say about it. People love this place, so I feel fine about sending you there and am confident you will enjoy boners.
