He said its weird, so now I cant confess.

There aren’t any suggestions to give. He’s not into it and it sounds like it’s a hard no.
But becoming pregnant for the sake of a kink is weird and irresponsible. Having a breeding kink is usually just the insemination and dirty talk around getting pregnant that most enjoy not pregnancy sex. So if that’s the case for you then just say it’s hot when you say xyz and it’s hot when you do xyz.

Maybe he isn't into having sex with you being pregnant for real but maybe he'd be open to trying roleplays about it with you? My husband is into that sort of thing but we're done adding onto our family so it's all pretend. If it's a kink that's important to you then I'd still share it, just prepare to be told it's a no and having to respect his answer.

there are online sex questionnaires for couples to answer together, some are even designed to only show each other your compatible results (so if you answer a question about being into breeding kinks but he answers no to it then it won't show your answer in the shared results, really helps avoid embarrassment or awkwardness when you both have different feelings about a kink)

I agree with Fairy, you can roleplay. Breeding/pregnancy kinks are not even always about the actual fertilization of the egg, it's the act of dominance and possession. If it's the actual baby that weirds him out, the fantasy shouldn't be too weird as you're not actually pregnant.

He’s not into it- so don’t tell him - done lol
