Husbands seamen smells horrible

Anon. bc he also has glow..

My husband's seaman smells absolutely awful, like something dead. It's sometimes yellow, and he says it hurts while he cums.

It's so bad that I refuse to have sex with him.

What could possibly be going on with him? -he will not go to the doctor; also, we've been trying for 3 years and no baby.. I'm confirmed fertile, but he refuses any testing..
