My husband's tight grey sweatpants

I just wanna know (REALISTICLY AND MATURELY) how others would handle this:

I already had an issue with these tight grey sweat pants my husband insists on wearing to the gym claiming they're comfortable. I let it go bc I'm just like whatever......(even though yes you can see his 🍆 print.

Well today someone I know who works out at the same gym as he does (a female) actually mentioned the pants telling me how he wears these tight grey sweat pants etc....I laughed out off but in reality I was embarrassed that it seemed like my husband was out here looking thirsty and I'm just stupid. He doesn't care. He laughed out off and swears by these pants. How do I appropriately react?
