Well... what it really boils down to is the theory of supply & demand.. Now, both sexes have a demand for the opposite sex; and there is a supply to match it..
From a woman's point of view.. They have a demand for guys.. and there is a certain supply of guys.. Let's look at how this market clears.. There's a (Price) so to speak.. If a guy want's too much, and has little to offer; then his (Price) is set too high.. and obviously.. we would all prefer quality & a lower price, which is now the case.. so the market will clear.. women will find men.. at the lowest (Price).. and those women that don't.. will have to wait.. until there is more available supply..
Now, let's look at the market for Women... Men have a certain demand.. and there is a certain supply of women.. Now, men have very basic criteria (looks, personality, fun, young, outgoing, smart, and sex is somewhere in there.. closer to looks and farther away from "loves pets").. So.. all these factors form a woman's (Price).. if a woman is lacking any of these to certain degrees; her (Price) is much higher.. [the opportunity cost of being with a lower quality woman, while higher quality women are available]... So.. all women are doing by "holding off on sex" for some meaningless and artificial reason.. is increasing their price.. and hence, remaining unsold.. the same can be said about b*tchy women, ugly women, etc.. So.. this market will eventually clear.. and women who are not purchased.. will have to wait.. and wait.. and wait.. and wait.. until some desperate guy who is willing to pay such a high (price).. [mind you, that's not a good thing; price is negatively correlated with the quality of the woman].. comes along and takes her out of the market..
Now, I personally don't care.. I've never been faced with this dilema.. but here is one thing to consider for both sexes reading..
Men (boys).. enjoy sex the most the first few times in their lifetime.. after the first few times.. all the other times are not as enjoyable.. (hence the need & desire to have more sex.. in search of that same initial pleasure)..
Women (girls).. take much longer to enjoy sex, and may not enjoy it early on.. But after those first few times, a woman starts becoming more familiar with her body and sexuality.. and more easily enjoys sex, and experiences more intense orgasms..
So, if it's anyone who should be "holding off" on sex; it should be men.. not women.. but.. like I said before.. this entire mindset and mentality is the result of 1000's of years of narrowminded cultures & the male dominated church trying to suppress women's sexual desires
