eh, sex is just sex, love is wanting to have sex with the same person over n over again without the effort to get a new girl. Thats pretty much the way i see it right now, i hope im wrong tho. "love" in other peoples mind seems to be something more, but all i can see it as, is infatuation.
I think it all depends on the situation, time of a person's life, what's important to them at the time. Some can go on having meaningless sex with others and they're satisfied (male and females alike) where as, others treasure the connection and relationship rather than the act itself. It is a generalisation that females can't usually have sex without getting their feelings involved however this is because females in general are more emotional. However, there are those who can control their emotions and enjoy sex as an act on its own.
