Possibly it's because I love being touched, especially my back and breasts, but I have an interest in lactation as a fetish. I don't know if I would really want to do this. Sounds like a lot of work before there are any results. A lot of work to keep it flowing and a lot of work if you have to lactate every few hours. That would especially make it into a chore or a duty, which isn't something I'd enjoy being stuck with on a regular basis.
Also, I don't think I could feel the same about a guy who sucked my breasts like an infant. In reality I don't see a male submissive as a child or lesser being that I need to guide through life and whatever else. I want someone who is on par with myself. He just likes to do what I tell him and get stuck in the odd cage now and then.
But, here for the interest, are some breastfeeding fetish links.
