Meh, I'll be honest: I do find it somewhat weird. i haven't been raised to think wrong of it or not, hell, I haven't even heard of males breatfeeding... hence why I find it a little off. But that's completely unfair for me to think so because I know I only find it odd since it isn't embraced by society, and well at least for me, society hasn't really even exposed the issue enough for me to hear about it.
I figure if I had the ability to breast feed already, to help out my partner, I would. And really I could care less if you do. What you do is your own business and frankly, I and no one else but you have the right to say anything, unless you're like harming the world, which, blatantly, isn't the case here.
