I [35F] discovered erectile dysfunction pills in my boyfriend's [41M] wash bag.

I recently discovered Viagra and tadalafil in my boyfriend's wash bag, and I'm uncertain about how to feel about it. We don't live together, so he brings an overnight bag with his toiletries when he stays at my place. To be completely honest, I found the pills while snooping through his things. I know I shouldn't have done that, and now I can't tell him what I found because it would break his trust. The issue is that the tablets seem to be disappearing when he's not with me. For instance, he recently stayed with family for a night, and upon his return, I noticed two Viagra pills and some tadalafil were missing. He also went on a five-day work trip overseas—I'm absolutely sure he was where he said he was—but when he got back, two more Viagra pills were gone. Over the past couple of months, I estimate he has used about six Viagra and four tadalafil tablets. I’ve never seen him take any of these medications before, nor had I noticed them in his wash bag until recently (since January). We're still being intimate, but I’m at a loss about what this means. Edit: 1. We’ve been together for about 14 months, and my partner has young children with whom I have a relationship. 2. I can’t explain why I chose to snoop, but now that I know about the pills, I can’t help but check if they’re being used. 3. I realize that my snooping makes me seem untrustworthy and less than ideal. I come from a history of abusive relationships, which has left me feeling incredibly insecure to the point of self-sabotage.
