I'm married and had an affair last year that lasted 2 months with one of my gym trainers. After an early morning session with a handful of people he asked me if I wanted to get coffee. Another trainer was there so he was able to step out for a few and told me I could drive with him. We drove to a Starbucks near by and placed our order, and we just clicked and started laughing and having a good time. We went back to the car and we were parked at a spot where there was no one else around in a side lot, and lucky for me he had an suv with dark windows. This man looked amazing and I jokingly asked him if I wasn't married if he'd thought I'd be his type. He told me I'm his type even if I'm married and I laughed. He politely asked if he could kiss me once since it's been driving him crazy thinking about it every time he sees me at our sessions. I was nervous and for a moment felt like I was 18 again and said yes.
One turned into us making out and then shifting into the back seat with me on my back and him between my legs. It was like having sex with an animal, touching his body and arms and holding his back. He's ripped and a bit heavy laying on top of me, but it was the best sex I've had in years. I went home and showered and spent time thinking about what had happened. I felt regret and sick to my stomach for a few thinking about what I did and being married. I never feel this way with my husband anymore. I remember at first it was like this, but things just became routine and there's no excitement. I called off the affair after 2 months since something in me changed and I felt cheap just sneaking around. He understood and never brought it up again, and my husband still doesn't know. Idk if I'll ever tell him since I don't want to hurt him, but I don't think this marriage will last since something just feels like it's missing and not sure if and how we can get it back.
