@chai2,
You can't have it both ways.
Nuh uh, I'm a man and I can be trusted to take a pill.....
Uh, are you going to do something to it to remind me if I forget?
I'm thinking perhaps the reason not everyone is as strongly opinioned about EACH person being responsible separately is that, well, most people either have at least one kid already, or expect to have a least one someday anyway.
Oh well, if I get pregnant, I was going to have one or some anyway, this is as good a time as any, and I'm pretty happy about it. At least I will be when I've got the baby.
But for those like me, and I know I'm a minority, the mere thought of getting pregnant is a forgein concept.
I'm not exaggerating when I say I'd rather get cancer than have had a child. At least with cancer you can work on getting rid of it.
Related to that, believe it or not, I have actually had more than one woman tell me that if I had a baby I would lessen my chances or breast, ovarian and I think cervical cancer.
My answer was "Yeah, but the problem is then I'd have a baby."
If you feel as strongly as I do about not becoming a mother, there's no way you won't take the responsibility on yourself, regardless of how careful the other person is, or say they are.
I may be a minority, but I'm definately not alone.
