Amazing sex showed me what I am missing with my partner

We get on pretty well and have even discussed having another baby. However, I don’t love my partner and I think I have known that for a long time. Our sex life is boring and I never climax. It did not really disturb me but two months ago, on a work training week, I had the most amazing sex with a man I hardly know. He is married and the relationship is not going anywhere, but I feel confused about how I responded. Should I end my relationship with my boyfriend?
After years of never experiencing an orgasm during sex with your boyfriend, I can understand why your body’s response that night must have seemed hugely significant. However, it is important to view what has happened in context. Having sex with someone else when you are in a committed relationship is exhilarating and unsettling; exhilarating because someone you are attracted to is attracted to you and that boosts your ego and your self-esteem; unsettling because of the risk that you might get caught.
