Here's the beautiful thing about a glory hole to space - you don't need anyone on the other side. The vacuum of space is the greatest viagra that you could come up with. The downside is that you aren't getting your little (or in my case, adequately sized) space cadet back once he experiences the infinite void. It's probably going to get so much blood that it explodes. But, boy will it be a cool send off for your little Yuri Bezmenov.

Also you don't have to worry that space is secretly a dude on the other side of that glory hole.
