I have just begun a passionate affair with my first ever boyfriend and have fallen head over heels in love. We are of course both married. I want to feel guilt so I can stop but don't. In completely celibate marriage and sex with ex is absolutely fantastic. I know I will end up with a broken heart but self preservation instincts have gone completely out of the window. Help me. He lives 100 miles away but this has not been a barrier so far.
