If you're looking for an illustrated how-to manual, but you get turned off by porn and explicit nudity, I have three suggestion for you this month.
I get a fair number of requests for instructional videos and books on three related subjects: erotic massage, hand jobs, and oral sex. There seems to be something about all three that makes people insecure about just winging it, and in all three cases, there are a lot of tips and tricks that many people never discover on their own that can make their partners' experiences much more enjoyable.
We're at a peculiar stage as a society where it is actually much easier to find porn, which is widely available for free of you are willing to search for it, than it is to find good non-pornographic visual materials to recommend. However, there are still many people who aren't comfortable with porn, or indeed anything too explicit, and there is much less in the way of good material for this group.
By coincidence, I have received two items in the last couple of months that should appeal to this underserved audience. The first is a tasteful and beautifully produced massage book, Erotic Massage for Couples: Head to Toe Techniques to Arouse and Gratify Your Partner, by Sylvia Patterson. And the second is an instructional DVD, Blow Him Away! by Dr. Sayaka Adachi, that provides a detailed guide to manual and oral techniques that you can use during lingam massage.
That makes this also a good time to review another book, Ian Kerner's She Comes First: The Thinking Man's Guide to Pleasuring a Woman, which is devoted to manual and oral techniques that you can use while giving a yoni massage.
