I have a friend who does this. I'm very open minded person and don't judge, but i've found it harder to be in contact since having lo, it's all to close to home so to speak. I think he finds it hard too, because I don't like 'baby' stuff like nappies thought of as sexy... He wanted to go baby shopping together, me buy stuff for Finn, him for himself, is where i drew the line.
He does only think of this stuff as good on a adult btw not children!
