Between [improved] diet and karezza I am experiencing life and emotions that I thought I would never feel and so quickly. Cleaning out is not easy - just as hard as giving up orgasm - but the benefits are just as substantial.
My wife and I now enjoy a much closer and much more fun relationship which gets better every day. It's like we have just met. I have got my sense of touch back. Previously I used to get very jumpy and irritable about touching to the point where i couldn't be touched at all. Amazing.

From The Erotic Mind by Jack Morin
p. 283 -4 My observations have consistently revealed an apparent contradiction: to preserve opportunities for lusty, passionate sex [assuming that's a goal], most successful long-term couples develop the ability to enjoy "warm sex." Rather than emphasizing focused intensity, warm sex revolves around calmer experiences of sensuality, affection, pleasure, and playful fun. Although warm sex usually includes genital stimulation, its goals are neither high arousal nor orgasm.
...Men are often troubled by warm sex because it doesn't necessarily generate sufficient erotic energy to produce or sustain an erection. Unfortunately, ...couples typically think the firmness of the penis the the indicator of how well things are going, an idea inimical to enduring sexual satisfaction.
...When erotic couples evolve out of the heat of limerence [the neurochemically enhanced honeymoon period], it's crucial that they find ways of keeping sex a priority.
