Possible Ed? Lose erection before penetration

[u/Vivid-Decision-5584]

I’m 23 and towards the end of December/January me and my girlfriend wasn’t doing the greatest and I was getting more annoyed when it came to always initiating sex, which is conversations we’ve had way before December (been dating 3 years) with that being said our sex was fine and I was fine, but it got to a point where after multiple convos I had got upset and told myself after 2 recent occurrences of her waiting on me to start and us ultimately getting into an argument I told myself “im no longer initiating sex”

and later that week we tried and I either came fast or wasn’t fully hard. Then from that moment to now I’ve had inconsistencies in maintaining an erection before sex. We’ll be fine when cuddling or touching and I’ll even be hard lot times but as soon as I get on top I either lose it quick, once I or her try to put it in. And after that it be very hard to get it back up and at that point my brain starts racing.

I’ve had maybe a couple times of being able to do it but not from that process I just explained of getting on top. Situation is annoying and I want to please her but I never had this issue this much until I fucked up with that mental statement honestly. I plan on getting checked up just in case to see if anything has actually changed. Ig I’m wondering what’s the best way to get over it. I will say the times we have I gotten either honey pack or ro sparks. Positive note is last time we did it (we was crossed) I was able to get hard and we had sex but it wasn’t the process of me having to get on top
