Yes, kissing is worse. If you ever watch porn it's just sex, very little kissing. It's just sex. But kissing is passion and romance and intimacy. And it's almost worse than fucking. Fucking is animal and primal. Kissing is emotional.
My WH spent the night with OW, it was 1 night. But all I can think of is the intimacy of sleeping next to another woman all night. She was all over him, caressing him, touching him, kissing him. She was "in love". My WH says he was there for the sex and she was a piece of meat. That makes me feel better. But I'm not sure I believe it. I keep asking him questions about that over and over again to confirm it. He said he didn't like kissing her and the sex sucked. I keep asking questions over and over again to make sure he's telling me the truth and not something I just want to hear.
