I just finished reading a book, "Men's Sexual Health: Fitness for Satisfying Sex," by McCarthy & Metz. It wasn't quite what I expected, but I highly recommend it. Especially if you are having trouble coming to terms with your natural sexuality.
It has a lot of good information in it, from help with your emotions to advice about how to introduce your kid to sex.
If you can buy the book, it is well worth it. If you're like me and you can't afford the book: I've provided a link to download it in PDF format. However, if you must download it, please support the authors by telling your friends about it and recommending that they take a look.
