Problems with ED drugs

Recently I took a 10 mg ceealis on three separate nights and had sex with my girlfriend, the first night was Saturday February 10th, the 2nd night was Wednesday February 14th, and the 3rd night was Sunday February 18th… I had great sex with her on February 10th and I orgasmed 3 times, on February 14th my erections seemed weaker and I only orgasmed once, and on February 18th I couldn’t penetrate and so I didn’t orgasm at all, it’s been two weeks since I took Ceealis and a lot of times I haven’t gotten much morning wood since and no spontaneous erections… I did get a little bit hard with my girlfriend but not even close to hard enough to penetrate the last couple weeks. My girlfriend is very understanding and patient with all this which is good. I’m currently on a 122 day streak away from PMO. We met in December and had sex once a week in January but I was on ceealis everytime but it worked fine then. It seems like the week I was on Ceealis in February hurt my natural erections and I know I didn’t have priapism because it wasn’t persistent or painful. Whenever I stopped doing sexual stuff with my girlfriend my erections would go down. I visited a urologist and she said there is no way I did damage to my penis and based on my research that makes sense. It’s weird to think I could of entered a flatline because that usually doesn’t happen to me after sex and it just seems like my blood flow somehow got messed up from ceealis. Has anyone else experienced anything like this?
