How to do a sexual energy exchange?

[AnthroHeart]

Is the sexual chakra where the feeling of the orgasm occurs?

The sexual excitation causes an activity on the red-ray chakra and it's notable a "fire" or "heat" on the bottom of spine. That's the sexual energy. The chakra wherein the orgasm occurs depends of the level the entity is unblocked.

Thank you Infinite.

So is it Tantra to move the orgasm point from lower up to the heart through releasing blockages?

I am releasing from my root and sacral chakras more recently since I learned what you were saying.
