Feeling Guilty

A few weeks ago I was out shopping and ran into an old boyfriend from high school. He was in town visiting family. I hadn’t seen him since we graduated so when he invited me to go for a drink I accepted. He was staying at a hotel close to where we ran into each other so we went there to the lounge.
We had a couple of drinks then I started getting sentimental about old days back in high school. We were never intimate.when we dated but when it was obvious he was flirting with me I got aroused giving him hints I was interested but he didn’t make a move.
After I finished my drink I told him I had better be getting back because it was getting late.
As we were walking out he took my hand then we ended up going to his room where we had sex for over an hour.
Now I’m having a real guilt trip because nobody other than my husband had ever came in me but I let him since my tubes are tied so there was no chance of him getting me pregnant.
