Sex in science fiction has been around for quite a while, and here are a few books you might have missed.
It had to happen, and so here it is for Valentine’s Day courtesy of TOR.COM, “SFF Sexier Than Fifty Shades of Grey” by Leah Schnelbach and Natalie Zutter. Some books and authors may be familiar, some perhaps less so, but for brief descriptions (accompanied by links for exploring further and, perchance to buy for oneself) please to peruse . . . but recommended only for those who are 18 or over).
