Th3y love having sex as they try to snag a man to stick around and support them, but hate the results/responsibility. Pure selfishness on their part. It’s not a “health issue”, but a “selfish issue”- kinda like Casey Anthony who would bind and drug her young child, stick her in the trunk of her car while she hopped up to a guy’s apartment to have sex. Her child was a bother to her evidently. Interfered with her mother’s party lifestyle.
Some are very ill rationalizing killing their babies. I liken them to cats who eat their litter.
