Allow me to recommend
Ray Gun Revival. My only affiliation with them is as a reader. They publish stories, both stand-alone and serial, in the style of Golden Age sci-fi. So far in twelve issues I've read, there's been no sex and less than a half-dozen mild curse words.
They've moved to a web-based format in their second incarnation, but you can still the pdfs of the original 57 issues in "The Vault" section of their forum.
