Does it matter WHY we want to have sex?

This has nothing to do with sexual assault or rape. So far, all sexual acts have been consensual. The issue is, a fraternity had a c9ntest about who could have sex with the most women. If their was a tie, the person who had sex with the woman who weighed the most, won. The frat was put on probation for 2 years. My question... should the reason behind sex really matter? If your okay with a 1 night stand, and so are they, do you care? If it does matter, why? If it doesn't matter, why?
