Daddy, Momma, Mami, Papi, etc. just makes me personally uncomfortable. I know there are a few reasons that people do it, which is fine, and if they enjoy that, that's fine, but it's not for me. I wouldn't want my partner calling me any of those things, and I wouldn't feel right doing that with them. For me, to be honest, I can get uneasy hearing it done, it's just an big uncomfortable turn off for me. Though, again, I get why some people do it, and any reasons I've heard for why it's done I can understand the thought behind.
