I'm having the same issue since whims became wants. My sim has had this long-term want for a while now, which is frustrating because I can't make her try for a baby with her wife without changing one of their gender options in CAS. This want shouldn't come up for sim couples that aren't "Get others pregnant"/"Become pregnant".
I'm having this exact same issue with my same sex couple. The option doesn't even populate in the socials wheel, yet it still pops up as a want. They really need to create a better filter for the wants a sim can roll. At least now I know it's not only me having this issue 🙃
