It's been a few years ... OK, 25 ..... but I used to ride daily. I remember gel seats being all the rage. When I got my new bike (mostly as a dust collector, of course) I got one of them holey sets. While it felt good in the shop, it "bit" on the road, so I got a gel saddle cover for it as well. It's just bearable in that configuration.
Try a few in the shop, but sit on it for more the a few minutes if you can.
BTW, nether region numbness from cycling is no laughing matter - that can lead to a serious medical condition. It's not so much that you need to harden up, it's that you need to avoid doing anything that stops you from ... ahem .. hardening up ...
