Intermittent erecctions

In my last 3 years, since I started to cycle with test, I had a sex frequency of 4-7 times a week. In the last year I had a frequency of 1 time per day, more or less, someday 0 others 2. Now I’m going out with two girls since may, and I do sex 2+ times a day. I meet with both in a day. But the problem started now in PCT, I get a very good and hard erecction, even after 2 times sex the same day, but the problem is, I loose the erecction during sex. I have to concentrate and get it up again, its bothering, and once its up, It Works wonders, and down again. Its kinda intermittent. I’m in my 2nd week PCT after 5 months cycle, don’t know if it has something to do with that, I have libido, because I need to do it, but I can’t hold it up for the whole session...

Maybe 2 times a day its too much when you’re off?? Or is it only in my head?

sometimes it gets down even when I'm about to get an orgasm...

thanks
