It ended when my son walked into the kitchen and my fiancé was having oral sex with a friend of mine.

Aftermath: It lasted long enough for me to allow him to pack his stuff.

It was over when I came home and found a Ziploc bag filled with poo left on my kitchen counter next to a note “Had a great time—you rocked my night! xxx” with her phone number. She had broken the toilet and I guess was too mortified to leave her business in the bowl, so she scooped it out, bagged it and forgot it on the counter.

Aftermath: I never heard from her again, but her roommate told me she was devastated. We really did have great chemistry, but in the end…

We were having sex and he asked me if I could “tighten my sh*t up.” I hopped off. He kissed my shoulder and passed out drunk.

—He was a good kisser

Aftermath: Never talked to him again.

He asked if the blow job I gave him the night before could have gotten me pregnant.

Aftermath: I spent a couple of weeks in denial before I finally broke it off, but I felt so much better once I did.

It was over when I told him that I needed a few days to myself because I was feeling smothered, then he sent me an instant message 8 hours later to see if I’d had enough time yet.

—Amy

Aftermath: I signed off AIM and ignored his calls that day, then I broke up with him the next day in person. He sobbed.
