Seriously, if she wants really hot gay sex, she should check out what's known as m/m romance: romance novels written by women for women about gay men. Say anything you want about exploitation and appropriation, it's totally explicit sex, hot as anything, AND you gets all the emotional connection you could want.
I'd suggest K.A. Mitchell, especially her COLLISION COURSE and NO SOUVENIRS. There's also James Buchanan, especially her (yes, her) HARD FALL, and INLAND EMPIRE, and THE GOOD THIEF. Also Brooke McKinley's SHADES OF GREY, Jane Seville's ZERO AT THE BONE, and Heidi Cullinan's SPECIAL DELIVERY. All of these can be found online and downloaded and read as e-books.
