Is it normal to not want to become pregnant but want to have kids/sex?

If you want children without to bother of carrying and child birth you could make a deal with a surrogate to carry and birth the child using an egg from the mother and sperm from the father. It's not new. It's being done a lot these days.

Totally normal, just a bunch of old fashioned -or religious- people in here. Sex is so much more than just making children, if you're in a relationship it's also about being close to your loved one.
we're living in the 21th century, women are allowed to enjoy sex without having to make an actual baby. GIRLS HAVE A CHOISE. and it matters. Just tell your partner your not planning on having them later in life.

A condition of marrying my wife was that I would not require her to use birth control, which as a very traditional Catholic, she has an abhorrence for. This way of life really opens my eyes to how powerful and life changing pregnancy and natural childbirth are for a woman and, by association, for her husband. Even if you don't fancy the idea of eight children (and counting) don't deny yourself what is one of life's most beautiful experiences.

It's not as normal as it should be.
Sex is great.
But, seriously. There's more than enough people on this planet.
