The Shape of Space: How to Visualize Surfaces and Three-Dimensional Manifolds by Jeffrey R. Weeks ...this one has been a good read so far, but it is quite mind bending, I only read like a half chapter at a time slowly, and then I have to spend some time contemplating. Cupid's Poisoned Arrow: From Habit to Harmony in Sexual Relationships by Marnia Robinson ...I just finished this one, and it has quite the interesting premise, and 300+ footnotes and references to scientific research, but I don't quite know if I'll be trying it out. The testimonials don't comport with my experiences, but they are somehow compelling. It is worth a read if you are looking for something different, and it definitely has some challenging thoughts to ponder. The main theory is that there is mammalian programming in your brain that releases oxytocin to make you feel good when you touch someone or engage in other bonding behavior. And there is a contrary effect that after orgasm your dopamine levels drop which causes people to get bored with their current partner and seek novel partners (to spread their gene further). The recommendation is to engage in intercourse, but avoid orgasm. And that it takes 2-3 weeks of avoiding orgasm to reset the neurochemistry in your brain, so that you get the blissful effects of oxytocin, without the dopamine depletion of orgasm.
