What utter nonsense. You can't seem to grasp the concept that many women want to enjoy the benefits of sex without the downsides.
The benefits of sex are the pleasureable union of the spouses, the sacrament, and potential children.
The downsides of sex only come from straying from ones spouse - disease, infidelity, guilt, and sin.
Apparently, you, along with Planned Parenthood types, consider children a "downside" of sex right there with veneral diseases.
Sex is very enjoyable without birth control. Trust me!
