Following two hours of stilted, uncomfortable intercourse in which the couple started and stopped at various times, Jeff and Kara DiMarco speculated Saturday as to whether they had just engaged in tantric sex. 'I'm pretty sure it was tantric,' said Jeff DiMarco, adding that he and his wife skimmed an Esquire article about tantra last month, and that what they did Saturday was 'like that, sort of.' 'We were definitely breathing together, and I know I didn't climax, even though I came close a few times. And I think we transmitted energy. Honey, we transmitted energy, right?' Wife Kara later told reporters that she was pretty sure her chakra had been stimulated at some point Saturday, but she couldn't say for sure.
