so sex is not the be all and end all of a relationship is it you need the other little things to give yourself to someone to be intimate and hence the sex is discovered with a stronger flavour and not the reason for the relationship at all.
Would you sleep with someone you only know for 5 minutes or would you at least want to respect her not to laugh at you and trust her not to broadcast intimate details.These are needed before sex and then sex is a cherry on the cake the finishing touch that makes all complete.
