Ladies, you are so right: no one, male or female, should ever allow himself or herself to be used for the mere pleasure of another. And, as a male, I would not ever want to "use" another person for my pleasure alone just as I would never want to feel myself being "used". Ordinary frendship is still the rock firm foundation of sexual friendship. Friends have a way of becoming more than just friends and then when sex happens it is because both parties are ready to "give" themselves to the other. The sex confirms the bond that has come to exist between two persons, which is hardly the kind of thing that seduction produces.
My friend, forget about "scoring"--instead, be open to the beauty and the mystery of human sexuality. It is there and the fantastic sex that those who "go for the gold" is there for those who respect themselves and all others.
