My husband masturbates to porn after we have sex

I just wanted some advice to see if I am looking too far into this and if I should bring it up to him or not. I (28F) would like to think I have a great sex life with my husband (31M). We have sex atleast a few times a week. I have a very high sex drive and sometimes I get in my head because I find that I am usually the one initiating/asking for sex and if I don't it won't happen. My husband struggles with ED problems so I think that could be a reason and he uses that as the reason of why he has a lower libido than me. Sometimes after we have sex I will try to initiate again after a few hours and he will make excuses saying he is sore and needs more time in between which is okay if I didnt see this. I have now noticed multiple times in the past month by accident my husband masturbating to porn on our camera around an hour after having sex and him finishing. Those times I had left for work and just wanted to check in on the camera as I do that pretty often since we have a dog and he knows this and when I saw this it made me feel like I am not good enough. I have been wearing sexy lingerie, giving him oral always and always making sure his needs are met sexually so it just feels embarrassing and like I do not satisfy him. Am I overthinking or should I bring this up to him? I don’t want to embarrass him but at the same time I feel like I’m struggling and I feel unwanted.
