If I get the message of Karezza correctly, orgasms during the first one or two years in a relationship are strong bonding factors.
After that it gets messy with the prolactin based behaviours that steers us towards separation.
Im wondering what should be the most proficient algoritm in a brand new relationship?
How about forming a deep bond with the help of conventional sex for a year (play it safe:) ), then switch to karezza method?
What do you think?
