End up In my feelings

I want sex or a form of sex all time but hardly ever get anything. She says she wants to want to, but when it comes down to it she just don’t feel like it… the other night we did but I got to rubbing her back and rubbing my dick up her ass Crack and
.. any way whe. It get to the point of gonna put it in i could feel it and new if I put it in I was gonna nut as soon as it gives in so I pulled back and just grabbed it and nutted… but most of time when we do have aex its not gonna last even a min once I put it in her

I have suffered with premature ejaculation my whole life. This app has helped me a bit I used breathing and tried to focus on all my 5 senses during sex last time and it helped. Also before penetration I squeezed my penis and it does help.

I am doing other things as well like HIIT training as ine study showed it helped with PE. I am very fit otherwise. I am also practicing reverse kegels which I tried during sex last time. This might sound odd but until recently I did not know that doing a reverse kegel can stop you from ejaculating. Do you know how to do it?
