have you ever chatted with a guy who wants to be a breeder?

Not me (being male anyway). But this is very common on the Whisper app, if you're looking for one.

There are plenty of male pregnancy/mpreg people out there

i already did. i wrote with a lot of guys who wanted to breed me. but i don't want to be bred by a stranger. for the most guys it is just a fantasy, too. the most ones are too far away (usa) and i'm in europe. that doesn't work. if i ever want to be bred, i seek for an active supporting father and partner.
