How to you stop thinking?

Hello all.

It seems that I am my own worst enemy. So here's what's going on with me

Used to have ED; cured ED; had many months of Divine sex with new GF; GF goes on vacation for 2 weeks; fap to pictures a few times (trying to practice edging and orgasm w/o ejaculation)

When she comes back, we have sex many times with no problems. Then one day I lose my erection before I can come.

The next time I get into bed with her, while we're just getting started and doing foreplay, as I get rock hard, I start to say the worst things to myself:

"You're not gonna be able to get it up"
"Do you even like this"
"You're probably asexual"
"This is weird isn't it"
"Yeah you're definitely not going to be able to fuck her"
"Pathetic as always"

Then my body gets all hot and by the time I get my clothes off, my erection is gone.

Most times, I'm able to get it back a few minutes later and everything will be fine (except for having an unusually hard time not cumming quick).

Regardless of the fact that I know I'm more than capable of having sex normally, everytime I go to have sex, I can't get my mind to stfu and stop spouting off bullshit.

Any of you deal with the same thing?

 

I'd been trying to explore different things I can do sexually, including maintaining erections after orgasming by separating ejaculation and a whole bunch of "sexual energy circulating" stuff. I was actually doing this while I was regularly having sex and there was no problem at all. In fact, I was way better in bed and sex was amazing.

I don't know what changed in that 2 weeks, but now I seem to be a mess up in my head and down there as well...
