Cheated on my BC 2 years ago and have never told him [F30] [M36]

I’ve only been with only a handful of guys. Middle school, high school, college, I was always in a relationship. Two years ago my manager announced he was transferring within the company. We had a goodbye celebration at a bar and after the goodbye ceremony during my drive home he sends me text saying “im only in the state for another two weeks” followed by a dick pic.

So I get home, park in the driveway, and couldn’t help but to look at the picture and damn. I mean I’ve worked with this guy for 2 years and occasionally glanced at his bulge but pawned it off as likely being due to good boxer briefs. So guilt started to set in for me. Like god damn, I’m always in a relationship, likely getting engaged here soon and this guy who not only looks like Johnny Sins but has a dick like him too wants to hook up before he vanishes from my life.

So it ate at me for 2 days but I gave in. Two days later I texted him back, told him that if my BF ever found out that I’d go directly to HR. He agreed. I went over there and I fulfilled my curiosity. Now I feel like I can finally settle down without any regrets and I’m not sure if I’ll ever tell my bf.
