My SO's cum smell so bad

I just started dating this guy and I truly love him, but honestly I hate the smell of his cum so badly.

I've been with other guys before and had no problem swallowing, but I can't even stand the smell when he took off the condom after we have sex without almost gagging.

I never told him I hate his specifically, just said I didn't like the smell of cum and would like to use condoms at all times. I cannot imagine having his cum inside me. It would literally make me throw up.

What should I do?
