Responsible breeding kink?

Hi! I kinda need some advice and/or want to share an inner conflict I recently had. I'm a firm believer in anti natalism and don't want to bring any children into this world. Now from the title you may deduce I have recently realized I have a breeding kink. For me it's completely about the fantasy and I don't want to actually become pregnant. I've been wondering about what form of contraceptive would work well while keeping up the fantasy aspect. I'm trans masc and don't want any hormonal contraceptive and condoms are out of the question. I'm 22 so I likely won't get an IUD and future testosterone therapy would probably make my uterine lining too thin for it to work anyway. So I've been wondering if there are any other people here in the same boat or who have any ideas. I want to live my life uninhibited but absolutely do not want to put children into this world. There must be a way, right?
