I kissed a guy Please Help shoud I tell my husband?

Please help there is this guy I’m attracted to and he is so attracted to me since I’m y and hot. We are on business trip. We end-up kissing each other. I know is wrong. However, while I’m on this business trip I found that my husband and his friend hired escorts for someone’s BD and I was hurt and this guy happens to be so attracted to me and so I’m I. I don’t know what to do know. I stopped him before it went further. However I never done anything like this before. Should I tell my husband when I get back as I believe in honesty during marriage
