Please do consider getting him neutered. It has a lot of benefits for the bunny as well as you and your family. A non-neutered bunny will be living in constant sexual frustration, and he's clearly already taking it out on you with the lunging and nipping at your feet. That's courting behavior - he is so desperate to mate that he's trying to get your feet to "fall in love" with him! (I guess there's just something about your feet he likes more than other feet!)
He will also constantly fear rival males coming into his territory, causing him to spray and poop everywhere, even on humans.
Neutering a bunny at an experienced bunny vet's can run up a few hundred dollars, but every penny out of my very limited student budget has been worth it. For one, a neutered bunny can be litter trained, keeping things very neat and pleasant. Secondly, he will not need baths and will still not smell at all. As long as his litterbox is changed twice a week, you will smell nothing but sweet hay, even if you bury your nose in his fur. Lastly and most importantly, he will be content, settled, friendlier, more easy-going, and no longer driven mad with hormones.
I know neutering rabbits seems crazy to a non-rabbit-person, like neutering a goldfish or something, but a pet rabbit isn't that far off from a pet cat or dog, and deserves the same humane treatment and quality of life. Hopefully you and your husband will reconsider!
