Have you ever cheated on your partner?

I'v never cheated on my husband and never will no matter how many temptations I have. (I haven't had one temptation yet and don't feel like I'v very easily tempted) but I did kiss another guy when I was with my first boyfriend. THings weren't going well with us and he was more into cars than he was into me, so I started having a crush on this other guy. We kissed and he gave me some hickies and I felt so horrible that I told my boyfriend about it. It was a terrible feeling. My boyfriends hands were shaking and he started crying, I had never seen him cry before. I could never hurt someone like that again.
