Fact.
They might even bring out something completely unexperienced before.
Try mixing an actual poison with another element, and you get the salt that you eat, and most of us cannot live without, and goats climb sides of cliffs to get to, risking life and limb.
Imagine that - something which actually kills, and another, becoming something that practically all of the 8 billion of humanity cannot do without easily. Except on doctor's orders that is. And, even then, they'd not not follow that order now and then.
When two people come together at that crazy level of intimacy, it all comes out. The connection creates a new outlet for things that both might never have known, been aware of or experienced about themselves.
Trust me, two new people are actually created.
A new resultant force comes into being, and draws the two irresistibly into a new being.
Go into it with caution.
Those who ended up taking the lives of their spouses or had theirs taken would have sworn it'd never happen when they first met, and all of the hormones were raging, and lust was highest.
Raw physical attraction doesn't necessarily mean compatibility, harmony or that the connection will endure.
Superficial basis for attraction and connection will wear off.
Always.
