I found male enhancement tablets in the bathroom...

So I found some male enhancement tablets in the bathroom... like placed somewhere that looks like they’ve been deliberately hidden.

Is my bf taking these because he can’t get it up for me without them ? I’m feeling really insecure now I don’t know if I want to talk to him about it because he might just think I’m having a go at him for it.

My ex had them when we were together but we actually bought them from the sex shop together because we wanted to see what would happen

Any advice ? I remember a few weeks ago I surprised him in lingerie and he couldn’t get it up so I’m wondering if that’s why? If so then that makes me feel awful, my own bf having to take tablets to get turned on
