How to delicately bring up a topic with Hubs.

I feel wierd for even posting this. I'm far from someone who ever asks for advice. It's usually I'm the one giving advice. But anyways. I think my husband may have toenail fungus and I'm having a hard time bringing it up delicately. Especially since he doesn't complain about it. And he's self concious about small things like this. One time I was trying to tell him he could use some of my facewash because it helped my blackheads and enlarged pores in my nose and he got upset and self concious. He's not a complainer so he could be in pain from his feet and not tell me. I'm not very good at being delicate! I can be blunt and bring things up at random times. I know what to try to solve the problem but bringing it up is hard. He's amazing and my best friend and has never pointed out any of my flaws. I don't want him to feel like it's a flaw. If I didn't think it was fungus I wouldn't care. I'm just worried about his health. I'm sure someone can sympathize. I feel rediculous asking but I'm a new mom who doesn't have many friends and I figured here was the best place. Thanks for anyone who can give me some tactful and gracious ideas.
