The fundamental biological purpose of sex is reproduction. Having sex while actively stopping reproduction is a simulacrum of sex--it's fake sex, not the real thing.
This is why everyone hates condoms. It's not simply because they're tight or they feel different--it's because everyone knows that they're not having real sex while using them. Our deep desire for real sex isn't satisfied.
The same is true for other forms of birth control. Deep down, our bodies know what's going on as our instincts are frustrated. People end up feeling unsatisfied, but they're often not quite sure why.
The solution to all of this dissatisfaction, naturally, is to have lots of real sex. No condoms, no birth control, no pulling out. Sperm has to flow into her uterus. That's the kind of sex that makes everyone happy.
If you're worried about babies, don't be. That's future you's problem--he or she can worry about that later.
