Does him taking viagra mean I don’t turn him on?

I found viagra in my partners draw when I was cleaning up.

When I try to initiate the sex I always get turned down so i always have to wait til he makes a move on me and goes ahead with it (which is hardly ever)

After finding the pills I’m thinking… does he have to prepare himself to have sex with me ? Do I not turn him on? Am I not attractive enough?

I confronted him about me not feeling attractive and sexy enough when he turns me down. He doesn’t say much about it .

I feel like if he actually has ED then it’s pretty selfish to let me keep thinking the problem is me and not tell me that it’s actually him who has a condition….
