help in bedroom

so uh i have a question, does anyone deal wjth their boyfriend/husband/significant other having erectile dysfunction?? so i do my boyfriends laundry sometimes and i was putting his underwear up and he had a pill bottle in the drawer so naturally i was curious cause why hide something in there? i wanted to make sure he wasn’t doing drugs or something crazy. but it’s pills for ED and he has problems getting hard or staying hard sometimes but he won’t tell me, he just says ‘im sorry baby it’s not you’ or ‘im just tired’ or ‘im just not in the mood sometimes’ but it’s clear he doesn’t want to tell me, any ideas on of i should bring it up to him that i’ve found the pills? i was hoping he’d tell me but he hasn’t
