Do you consider having sex with your partner to be something that you do to

[Dude]

please them? My wife has explained to me that she has sex with me to try and please me. I felt a little put off by that but I couldn't exactly put my finger on why. I kind of think that sex is more about passion, love etc ... than her "pleasing me". That makes it sounds like she is doing a chore. I'm interested in other perceptions on if you have sex with someone to please them??
