l-hedoniste speaks the truth. Sex can only improve a good relationship, but it can destroy a bad one. Shantalla's opinion is largely a collection of cliches based on the track record of relationships that were doomed to fail from the start. Women are in large part the only people who think women are "easy" if they have sex "too soon". We guys don't think like that, unless we're ONLY after sex. Very few guys fit this description, and when they do you'll usually know in advance from their reputation. Guys, excluding self-righteous moral uprights, don't often judge a girl based solely on how long they resisted the temptation to have sex. Hell, more often than not we think a girl who refuses to have sex is just playing games, stringing us along, and/or trying to milk us for cash and gifts.
Oh, and this 'men are hunters so don't have sex with them for # months' stuff is just crap. If you like the guy and want to have sex with him, HAVE SEX WITH HIM! It's what you want to do. Don't fail to be yourself in an attempt to live up to the standards of someone else.
