I need to make a guy whose a lot more masculine to mpreg the hell up.

I need to create a total bear that everyone thinks is finally just getting a beer gut, or settling into a hravier middle age body, and the closest they get is saying he's getting a dad bod, because THEY AREN'T WRONG. No one thinks he'd be the pregnant one. Maybe they even look PAST him and say that his partner is "so thin for being pregnant!" and that they "need to eat more to get meat on those bones!" (The best, silliest situation for sympathy weight gain ever ajdjakdkka)

I just need... a more masculine guy... and I need him so knocked up.
