I only really know about tantric sex because of some comment Sting allegedly made in 2004. He later blamed the misinformation on Bono, claiming he said he and Trudy Styler have "frantic sex" not "tantric sex." It doesn't really matter at this point because there are lots of celebs who claim to be all into it. I'm looking at you Heather Graham.
Dubbed "the gateway to ecstasy," tantric sex is an ancient Hindu practice that encourages couples to prolong intercourse in order to build up to a more intense orgasm, or orgasms. It includes any kind of touching that encourages deep intimacy.
Basically, it's about having sex while making eye contact and breathing together and feeling the connection. So, instead of rolling your eyes back into your head and thinking about when you're going to get off, you're, like, being mindful of each other.
