Have you ever made a bad decision, been influenced negatively or done anything foolish because the sex was good?

in the mornings, i listen to this morning radio show where people write in letters looking for advice. it seems that many of the letters are from women discussing their significant others, how they suspect them of cheating, lying, etc. but when the writers discuss why they stay in the relationship with the cheater, many times they mention good sex (and then the radio host points this out to them and talks about how stupid they are). have you ever been influenced to do the wrong thing or make bad decisions based on (or partly based on) that the sex was good or this person was a good lover?
