That really depends on your definition of “cheating”. I have lots of sex with people other than my husband, so many would consider that cheating, but we don’t. Some people feel that if you ask permission or inform your partner beforehand that it isn’t cheating. Well we both just go and do who we want, when we want, and may bring it up to the other later!
I did cheat on my husband about 25 years ago. He was going to university all day, and worked all night, so he would sleep in the evening. One of our neighbours had a wife who worked evenings, so he and and I spent a lot of time together. We ended up fucking almost every night for about 6 months and I never told my husband about it until close to 10 years later. So that really was cheating.
These days, I may invite a guy over for some fun and totally forget to tell my husband. More than once has he walked in on me fucking a strange guy 😉
