Tantric sex is, of course, fundamentally rooted in a spiritualist practice, and thus can seem a bit esoteric and inpenetrable someone unfamiliar with it. Although the ideas and principles in the philosophical underpinnings are good to know, you probably want to get started with understanding what you do and what you could expect to get out of it. Then once you start to enjoy it, you can delve in it deeper.
In general Tantra can be thought of as the practice of developing deeper sexual intimacy and reaching altered states of consciousness through sexual connection and pleasure. The practice contains several elements:
1) Exercises and rituals. In general maintain an attitude of exploration, physically exploring every body part of each other, and trying a variety of stimulation everywhere. Talk regularly about what you’re experiencing during intimacy, what you see, feel, smell, etc.
A good selection of exercises is given in the following book.

It has everything from getting used to prolonged eye contact to rubbing yourselves with oil and sliding across each other.
2) Tantric Sex itself is done generally either lying on top of her or sitting with her on top of you for a prolonged period of time, the thrusting done very slow. Get into a steady rhythm, it should become meditative. After you’re used to it, try synchronizing your breathing together activelyand if you’re feeling wacky also imagine visualizations of shapes and colors in your bodies centered around where you are inside. With enough practice there should be a sense of erotic one-ness, especially if you practice #3, and especially as you reach a long contiguous time inside (30-60min+)
3) The overall Tantric practice involves fairly frequent intercourse and general stimulation, with the woman having as many orgasms as she likes while the man holds off ejaculating (so women reading this, get your man on it!). Of course, like with anything, it is recommended to go slow in reducing your frequency of ejaculating. At the most I’ve gone 6 days straight having sex at least twice per day and not ejaculating, and by the end it feels like an energetic high, kind of like very pure coke, where I felt powerful, euphoric and hyper-aware. But I’ve heard of people going 20 days like this and more (although it’s recommended you ejaculate at least once per week on average in the long run for prostate health).
For the woman, the peak of experience I’ve witnessed is her entering into a prolonged orgasmic state with pulsating sensations moving across her body, meanwhile hallucinating various images in her mind. Pretty awesome, but unfortunately I haven’t yet recreated that in anyone since that time. But otherwise the Tantric practice still brings a lot of joy and pleasure and increased intimacy. At the least they feel closer and it improves the sex overall, and otherwise the Tantric sex itself can be relaxing and awakening at the same time. It does deliver on the promise of taking you to experience some interesting and pleasant altered states of consciousness together with an intimate partner, thus bonding well in the meantime.
