Per the catholic church abortion is wrong , premarital sex is wrong. but that is one of the questions on this site.
Birth control is wrong except for rythm methode( maybe that has changed)
Viagra when used by men outside of their marriage to enhance sexual performance should also be wrong.
If we believe that women become pregnant by God's grace and all babies are a gift from GOD because they are truly precious. ( Which I truly believe)
Should we not also believe that if we are not able to conceive or procreate. ... GOD has a reason?
If the above is true than If a man no longer can " preform" then maybe GOD has a reason for that too?
I'm not saying any of the above is right. I just think it is something to think about.
No..It's not something to think about.. Most impotence occurs in older age men, but can happen in younger.. But lets assume that it's only in older married men with wives beyond the age of procreation.. Should he stop having sex with his wife because she can no longer have babies? Sex is also unitive. So you want to deny a married woman the right to be in a unitive embrace with her husband because non married people use it too?
