I currently have a good thing going with a plate except I am unable to get it up like 75% of the time.

I will usually be hard during foreplay, but the moment I change positions and I'm about to put it in, I lose my erection.

Out of about 12 times, I have only been able to fuck like 3 times. But I am always able to get hard and finish from a blowjob.

I am dealing with whatever is causing the ED (Most likely porn-induced or some other psychological thing) but I am curious as to whether I should have an open communication about this with her?

I went to the doctor who claims it might help to get pressure off me (which could help with me overthinking it in the moment) by talking about it with her. r/relationships and r/sex also emphasize strong sexual communication. However, talking about negative things about myself seems blue pill to me and would likely lead to her having a negative sub-conscious emotional response, so I'm not sure how I should approach this.

I am mainly looking for advice on how to go about communicating with the plate. But any advice on getting over ED is helpful too.

Thanks
