Boyfriend said I have an odor

My boyfriend told me a leave a little odor on his penis and I need to fix it. I have no infections and I eat healthy and I take at least 3 showers a day. We recently started trying for a baby and he thinks his cum has to do something with the odor. I never had this problem before. He tells me I need to get something to fix it. Sometimes we’ll have sex after he’s been out all day. This really makes me feel so self conscious about myself now.

What is this because he sent this to me
