Reddit reviews Jewel in the Lotus/The Tantric Path to Higher Consciousness

I know of no kundalini yoga books dealing with sexuality specifically.

Reddit has no kundaliniyoga subreddit, so I'm unsure how many of their practitioners might explore here in /r/kundalini. Kundalini yoga is more about growth over-all in a smoothened gentle but rigorous method. You might google for a kundalini yoga forum and ask there.

I am more than familiar with kundalini, and have explored the tantric path. Most tantric paths and yogas have, as an aim, to awaken or stir up kundalini.

Kundalini isn't usually done in order to improve sexuality nor libido, yet those can be side effects.

Some Tantra-focused books with good foundations for kundalini that I've read which you might find useful. They don't go deeply into the kundalini topic as "an exhaustive treatise".

• Jewel in the Lotus.
  
• The Art of Sexual Ecstasy.
  
• La Célébration Sexuelle Still untranslated - French only.
  
  In my experienced opinion, the best book on kundalini by far is:
  
  Kundalini and the Chakras: Evolution in this lifetime
  
  Tantra comes in three main flavours. White, pink and red. White focuses on spirituality, with increased pleasure as a bonus. Red focuses on increased pleasure, with spiritual growth as a bonus. Pink is the middle ground between the two. Books don't usually claim to be one or the other. Experienced teachers help define it for students.
  
  Any of the tantric or yogic exercises will do several things including decrease stress and increase your prana or life energy. It's not uncommon for those factors alone to raise libido and sex drive, at times unpredictably. Add the exercise, oxygenation, muscle tension release and circulation effects and you have WOW!!
  
  The idea is to let the effects of the energy increase bring benefits to more than just your sexuality. You should be open to benefit on many levels. Yes?
  
  If you're experiencing whacko libido levels, it is also possible that you've stirred kundalini up to the second chakra (counting chakras depends upon the chakra system - there are many variations and understandings), which is responsible for sexuality, reproduction, recreation, creativity, etc. This is the one about half-way between your pelvic bone and your belly button. If so, learning what it means to raise or draw the energy to chakras higher up the body can be useful here.
  
  If one is going to explore kundalini, then it can be more than helpful to be aware of and practicing some of the supporting wisdoms. These can be from either yoga (Namas and Niyamas) or from Taoism / Buddhism / Zen. A glance in wikipedia can get you started, or the sidebar in /r/meditation.
  
  Various kundalini approaches make no requests for you to be a prude. The idea is to find a healthy balance. Occasionally, the practice of Brahmacharya, or non-sexuality, is used to highten the tension and possibly provoke more energy to direct itself in a kundalini-stirring direction. It could be useful for you to understand some of the methods and intentions of Brahmacharya.
  
  Having experience in any or several varied meditation practices is almost an essential prerequisite to a good kundalini experience. Nothing beats taking courses with living beings to build a good foundation to your practice. In this case it doesn't matter as much what form you choose, but that you do choose, learn, play, and develop a deeper understanding of mind, self, etc.
  
  Be aware that the techniques listed in the books can bring about significant advances involving lots of change, and inspire the kind of growth one might prefer to have support going through.
  
  ============
  
  Some books I've only glanced at and was not drawn to buy nor read fully at the time - several on this search list.
  Amazon search
  
  You could explore some Osho books, though I recommend his books with some caution as he was considered by some to not bother passing on the wisdom that was meant to go with the techniques he taught. It's apparently one of the two reasons he was booted out of India, and perhaps related to the paranoia that some of his students expressed in Oregon. Still, his writings are fresh and fun, and he had a brilliant mind. He wrote many dozens or hundreds of books, and I've read but a half-dozen, so you're on your own on this author.
  
  Also to consider: Kriya yoga and pranayama.
  
  I haven't done any Bikram, so have no idea if pranayama is a part of their practice.
  
  Good luck.
