Chemistry is important. No doubt about it. One beautiful thing regarding chemistry is the fact that it does not take long at all to surface. Nature speaks by itself. It s like wine, you hate some sort and you like some sort of wine. Nothing you can do about it, it s in your DNA
Although it is important to observe that PLEASURE does not necessarily involve chemistry. even some wine you hate can give you great pleasure (for example when it s the only one you are able to get). And human is more complex than wine. You can have pleasure and fun without chemistry. So no one should be chasing for chemistry when dating SPs. It is not required.
