Yeah I agree with that.
When I read his story, remind me my first punt years ago.
Not enough sleep and can't get hard enough while inside the wl, and end up not finnish. And feels meh, but as I keep going. It become more enjoyable,and now become addictition. Lol
@op
Like I said before, don't feels down, plenty of the bros here had been there before.
Maybe you need to have longer session.
Or maybe you need some new experience , like after you pounding and feels your knee hurst or tired, try pulled of and ask for cim, and you wanking your self until you almost blow the load and tell her almost the time and ask her to bj you. Maybe with the new sensation like this you have something to chase as a target. But in time for hopefully you can get the deed done under 1 hour.
But same suggestion, abstain from wanking and porn. If you want jerk off, use a lot of lube and do it slow, because in reality vagina muscle and mouth muscle cannot keep to hand muscle. You need to adjust your body back to normal.
Good luck
