^^ Then in summary, you are still condoning the act of abortion. Thats what Pro-choice for me is all about. Its a personal CHOICE, not a referred suggestion.
Abstaining from sex? Well, i think couples who already have many children should abstain, specially those who are in and below the poverty line. So if they plan to make another one(baby), they should be sure that they will live it, i mean won't abort it.
The gist of my statement in relation to this, is they want to do the act and the result came UNPLANNED (hence they never wanted to make another baby)
Well, the problem here are two things, one, either they have a lot of time on their hands that sex seems to be a cheaper alternative to spending some bonding time together, or two, its an act they share to strengthen their marriage.
In either case, there are alternatives to achieve similar results, however, it does not equate to the same degree of bonding they get when they do the act. Its a complex explanation if you are not yet of that mature age. Let me tell you this though, there have been some studies that performance in sex does have a significant factor in keeping the fidelity and happiness in marriage.
