i think that it all depends on a the girl. Some girls are slags but i know alot that want a serious relationship before sex; not necessarily marriage but at least a commitment of a year b4 they even go past 2nd base. personally i'm like that but i know alot of girls who arent. i also think it's more fulfilling if you do it with someone who u really like and treats you well with respect even if you dont love them.
